* Fixed problems with replication and virtual domains.
* Fixed problems with newer cyrus.index files on 64-bit machines.
* Added '-p <ssf>' option to services so that PLAIN authentication
can be used without TLS in secure environments.
* Added munge8bit to control whether unencoded 8-bit characters in
headers are changed to 'X' or are left alone.
* Added sieve_allowreferrals option to control whether timsieved
issues referrals or proxys traffic to backends.

MODSEQ).
* Fixed imtest to be compatible with SASL 2.1.22.
Changes to the Cyrus IMAP Server since 2.3.4

Changes to the Cyrus IMAP Server since 2.3.3
* Added support for BINARY APPEND (including CATENATE). Based on
contributions from Tom Esh <esh@lucent.com>.
* Added support for CONDSTORE (must be enabled on a per-mailbox basis
with the /vendor/cmu/cyrus-imapd/condstore mailbox annotation.
* Fixed bug in reconstruct using bad name for cyrus.header.
* Fixed bug with replication and default partition.
* ctl_mboxlist now dumps/undumps the mailbox type flags, making it
useful for remote mailboxes.
* Better logging to facilitate message tracking (Wes Craig
<wes@umich.edu>).
* Implemented CAPABILITY response in banner and after authentication.
* Fixed miscellaneous bugs and build issues.
Changes to the Cyrus IMAP Server since 2.3.2
* Fixed broken berkeley (btree) backend.
Changes to the Cyrus IMAP Server since 2.3.1
* Added more extensive output to arbitron.
* Allow responses of any length from backend when proxing
IMAP/POP3/NNTP traffic.
* Properly handle timeouts when proxying.
* Added plaintextloginalert option.
* Fixed segfault in deliver.
* Only allow mbpath to be run as Cyrus user.
* Added nntptimeout option for nntpd.
* Added berkeley_hash and berkeley_hash_nosync cyrusdb backends (seem
to perform better under heavy loads).
* Added TLS support to cyradm.

Changes to the Cyrus IMAP Server since 2.3.0
* Updated ACL code to RFC 4314 (separate rights for message delete,
mailbox delete, and expunge).
* Fixed IDLE to use idled for local mailboxes.
* Fixed miscellaneous build issues.
Changes to the Cyrus IMAP Server since 2.2.x
* Added support for "unified" and "replicated" Murders. A Murder no
longer has to have discrete frontend and backend servers; any one
"unified" server can both proxy and serve local mailboxes (proxy
functionality in proxyd and lmtpproxyd has been merged with imapd
and lmtpd respectively), or all "replicated" servers can serve the
same mailboxes from a shared filesystem. The new mupdate_config
option in imapd.conf is used to determine whether a Murder is using
a "traditional", "unified" or "replicated" configuration.
* Ported/rewrote/integrated David Carter's mailspool replication
code. Development sponsored by Columbia University.
* Added support for "delayed" expunge, in which messages are removed
from the mailbox index at the time of the EXPUNGE (hiding them from
the client), but the message files and cache entries are left
behind, to be purged at a later time by cyr_expire. This reduces
the amount of I/O that takes place at the time of EXPUNGE and
should result in greater responsiveness for the client, especially
when expunging a large number of messages. The new expunge_mode
option in imapd.conf controls whether expunges are "immediate" or
"delayed". Development sponsored by FastMail.
* Added support to place some/all mailbox metadata files (cyrus.*
files) on a separate (probably high-speed) partition. See the new
metapartition and metapartition_files options for details.
Development sponsored by FastMail.
* Added support for accessing subfolders of INBOX via POP3. See the
new popsubfolders option for details. Development sponsored by
FastMail.
* Added support to lmtpd to do "fuzzy" mailbox matching on
user+detail addresses. See the new lmtp_fuzzy_mailbox_match option
for details. Development sponsored by FastMail.
* Added new sieve_extensions option to allow individual Sieve
extensions to be enabled/disabled.
* The Sieve "include" extension is now supported. This also allows
for global sieve scripts. See the new sieve_extensions options to
enable it.
* The Sieve "body" extension is now supported. See the new
sieve_extensions option to enable it. Development sponsored by
FastMail.
* The $text$ variable for Sieve notify messages is now supported.
Development sponsored by FastMail.
* The MIME structure of a new message destined for multiple
recipients is now only parsed once rather than once per delivery,
resulting in better performance. Development sponsored by FastMail.
* Support 64-bit quota usage (both per mailbox and for the entire
quotaroot), based on a patch from Jeremy Rumpf. Development
sponsored by FastMail.
* Added new flushseenstate option which causes imapd to immediately
flush changes in \Seen state to disk rather than caching them until
the mailbox is closed. Enabling this option may fix \Seen state
weirdness with MS Outlook, at the expense of
performance/scalability. Based on a patch by John A. Tamplin
(jtampli@sph.emory.edu).
* The Sieve "copy" extension is now supported.
* The IMAP "CATENATE" and "URLAUTH" extensions are now supported.
* Updated Sieve "vacation" extension to draft-ietf-sieve-vacation-04.
* Added support for Sieve scripts on shared mailboxes via the
/vendor/cmu/cyrus-imapd/sieve annotation.
Changes to the Cyrus IMAP Server since 2.2.13
* ctl_mboxlist now dumps/undumps the mailbox type flags, making it
useful for remote mailboxes.
* Added sieve_allowreferrals option to control whether timsieved
issues referrals or proxys traffic to backends.
Changes to the Cyrus IMAP Server since 2.2.12
* Allow sieve scripts to be run on shared mailboxes (via sieve
annotation).
* Updated nntpd to be compliant with latest draft (soon to be
RFC3977).
* Updated IMAP UIDPLUS extension to be compliant with latest
specification (RFC4315).
* Performance improvements to quota utility.
*
* Fixed possible race condition in IMAP IDLE.
* Made ptloader runtime configurable.
* Added more extensive output to arbitron.
* Allow responses of any length from backend when proxing
IMAP/POP3/NNTP traffic.
* Added plaintextloginalert option.
* Only allow mbpath to be run as Cyrus user.
* Added berkeley_hash and berkeley_hash_nosync cyrusdb backends (seem
to perform better under heavy loads).
* Added lastpop mailbox annotation.
* Added subscribe/unsubscribe support to cyradm.
* Fixed miscellaneous bugs and build issues.

Changes to the Cyrus IMAP Server since 2.2.10
* Fix possible single byte overflow in mailbox handling code.
* Fix possible single byte overflows in the imapd annotate extension.
* Fix stack buffer overflows in fetchnews (exploitable by peer news
server), backend (exploitable by admin), and in imapd (exploitable
by users though only on platforms where a filename may be larger
than a mailbox name).
Changes to the Cyrus IMAP Server since 2.2.9
* Fix 0 termination in mysasl_canon_user.
* Check for imap magic plus buffer overflow in proxyd also
(CAN-2004-1015).

different from the last ALERT, or we haven't sent an ALERT in over
10 min.
Changes to the Cyrus IMAP Server since 2.2.8
* Change ACLs correctly when renaming a user
* Do not abandon std{in,out,err} file descriptors; syslog assumes it
can use stderr if syslogd isn't running.
* Clean up imap magic plus to avoid buffer overrun (CAN-2004-1011)
* Fix lack of bounds checking in PARTIAL and FETCH (CAN-2004-1012,

read).
* Fixed off-by-one error in fetchnews (articles are no longer
skipped).
* nntpd now uses the Followup-To: header (if exists) instead of the

Changes to the Cyrus IMAP Server since 2.2.2
* Berkeley DB 4.2 Support - note that the Cyrus Berkeley enviroment
needs to be reset (db_recover) before a Berkeley DB version upgrade
or you need to remove all berkeley dbs. Special care needs to be
taken when berkley db is used for mboxlist.
* Runtime configuration of the Cyrus databases. The cyrudb backend
used for each database can be specified with an imapd.conf option.
NOTE: You MUST convert the database using cvt_cyrusdb BEFORE
changing the backend in imapd.conf.
* Sendmail socket map support (smmapd) for verifying that mailboxes
exist and are deliverable before accepting the message and sending
it to Cyrus.

* Removed deprecated LAST command from pop3d.
* Sieve Bytecode is now stored in network byte order, meaning that
bytecode files can be freely moved between different platforms
* Sieve relational extension now working again.
* Sieve vacation now uses the correct subject.
* A large number of bugs involving virtual domain support have been
fixed, including issues with the Murder, and with Sieve.
Changes to the Cyrus IMAP Server since 2.1.x
* There have been extensive performance and consistancy changes to
the configuration subsystem. This will both ensure greater
consistancy between the documentation and the code, as well as a
more standard format for specifing service-specific configuration
options in imapd.conf. Important changes are detailed here:
* The tls_[service]_* configuration options have been removed.
Now use [servicename]_tls_*, where servicename is the service
identifier from cyrus.conf for that particular process.
* Administrative groups (e.g. admins and lmtp_admins) no longer
union, service groups completely override the generic group.
* lmtp_allowplaintext is no longer a defined parameter and must
be specified using the service name of your lmtp process if you
require a specific value
* libcyrus has been split into libcyrus_min and libcyrus, so as to
allow sensative applications (such as master) include the least
amount of code necessary for operation
* Virtual domain support. See the virtual domains document for
details.
* Users can now be renamed (even across domains). Note that this is
not atomic and weirdness may occur if the user is logged in during
the rename. See the allowusermoves option in imapd.conf(5) for
details.
* The db3 and db3-nosync database backends have been renamed to
berkeley and berkeley-nosync respectively (to avoid confusion over
whether or not db4 is supported).
* The default mailbox list and seen state database formats have
changed to skiplist from Berkeley and Flat, respectively.
* ptloader is now a regular cyrus service. This has several
implications, see install-upgrade.html for more details.
* NNTP support. Usenet news can now be fed to and read from Cyrus
directly via NNTP, without the need for a local news server. See
netnews document for details.
* IPv6 support, provided by Hajimu UMEMOTO <ume@mahoroba.org>
* Sieve scripts are now compiled to bytecode to allow for faster
execution (and lmtpd no longer needs lex or yacc). See
install-upgrade.html for more details.
* The functionality of pop3proxyd has been merged into pop3d. Be sure
to update cyrus.conf on your frontend machines accordingly.
* The functionality of ctl_deliver -E has been moved to cyr_expire
-E. Be sure to update cyrus.conf on your machines accordingly.

options)
* Berkeley DB Configuration methods have changed. Hopefully they're
more generic now. You can still use --with-dbdir, or you can use
--with-bdb-libdir and --with-bdb-incdir
* timsieved now handles usernames with dots (when unixhierarchysep is
active)
* tugowar has been removed from the distribution.
* Squatter now has an option to skip unmodified mailboxes.

* The normal assortment of small bugfixes
Changes to the Cyrus IMAP Server since 2.1.4
* Sieve is no longer dependent on duplicate delivery suppression (it
still uses the duplicate delivery database however).
* Sieve now supports draft-segmuller-sieve-relation-02.txt
* imtest now includes all the functionality previously kept in
pop3test, lmtptest, smtptest, and mupdatetest. imtest will notice
if it is invoked with one of these names and do the right thing.
The -P flag can be used to force a particular protocol. As part of
this, the default install location for mupdatetest has changed to
be the same as the other test utilities. imtest also includes new
MANAGESIEVE functionality (sivtest) as well as the ability to
reconnect to the same server multiple times (useful for testing
SSL/TLS session caching and DIGEST-MD5 fast reauth).
* snmpgen generates stubbed out code so we don't waste resources on
something that just doesn't work. At some point in time, we'll make
it work again as it would be useful to gather aggregate statistics
on what commands are being used so we can better tune the server.
This change closes bug #1191. New bug 1267 opened to re-enable the
feature.
* Added the chk_cyrus program to help point out missing message files
and/or mailboxes
* ANNOTATEMORE improvements. Server annotation support has been
added. We are also now using the /vendor/cmu/cyrus-imapd hierarchy.
The "info" command in cyradm now returns annotations for the given
mailbox (provided that ANNOTATEMORE support is compiled into the
server)
* The RENAME command has been almost entirely rewritten. Now we rely
on mailbox-level locking instead of locking the entire mailboxes
file for the duration of the rename. ctl_cyrusdb -r now also cleans
up "reserved" mailboxes that may appear in the event of a crash.
* ctl_mboxlist can now dump only a particular partition
* The configuration subsystem now uses a hash table to speed up
lookups of options. Additionally, the hash table implementation has
been updated to possibly take advantage of memory pools.
* Many bugfixes related to the Cyrus Murder. Includes improvments to
subscription handling as well as correct merging of seen state on
mailbox moves.
* Can now configure an external debugger (debug_command option in
imapd.conf.
* Misc. autoconf-related fixes (most notably those related to
sasl_checkapop and O_DSYNC).
* Misc. locking-related fixes.
* Security fixes related to handling large literals in getxstring(),
as well as correct usage of layers in timsieved.
Changes to the Cyrus IMAP Server since 2.1.3
* All "MAIL" and "SIEVE" notifications are now handled by notifyd
which is a daemon that supports multiple notification methods. The
mailnotifier and sievenotifier options have been added to
/etc/imapd.conf to configure notifications. (Ken Murchison)
* Many feature enhancements and bugfixes for the Cyrus Murder. The
code now supports live (but not transparent) moving of mailboxes
from one server to another.
* Some warning fixes.
* fdatasync() is no longer required.
* Fixed a bug in imap/append.c that would show itself if a message
was being delivered to five or more different partitions.

tmpfile(); the staging directory is used instead. (Ken Murchison)
* Fix a possible crashing bug in squatter. (Ken Murchison)
* Deleting a user now also removes their Sieve scripts.
* cyrusdb_skiplist: release locks during iteration. Should prevent
denial of service attacks and possibly increase performance.

is possibly faster on Solaris. Currently off (it seems to hurt
performance on Linux).
* master has preliminary code to avoid forking storms.
* sieveshell should now loop through all available SASL mechanisms
before conceding defeat.
* sieveshell can now upload a file to a different name.

adkinss@ohio.edu.
* fixed some memory leaks in imclient and in the Perl IMAP module,
prompted by Toni Andjelkovic toni@soth.at.
* fixed a longstanding authentication error in the Perl IMAP module,
should remove pesky extra Password: prompt.
* fixed some allocation bugs in the managesieve perl module.
Changes to the Cyrus IMAP Server since 2.0.14
* fixed memory management bugs in imapd, lmtpd that were being hit
due to the connection reuse code and causing subtle and annoying
problems.
* we now clean up better when deleting a user
* fixed an endian bug in ipurge
* pop3d now can also reuse processes.
* fix a bug in imclient that would strike when cyradm specifies a
mechanism on the command-line. (SASL mechanism names aren't case
sensitive.)
* fix some bugs in handling SIGHUP in master
* fix a couple of goofs in Admin.pm
Changes to the Cyrus IMAP Server since 2.0.13
* fixed a silly bug with reusing SSL connections
* lmtpd can now service multiple clients in sequence, hopefully
improving performance
* changed how Berkeley db databases are opened, hopefully lessening
the chance of deadlock and improving performance
* fixed a couple of memory leaks
* lessened the chance of a race condition during index_check()
Changes to the Cyrus IMAP Server since 2.0.12
* refactored code so less duplication
* added alternate config file for partial virtual domain support
* pop3d can now disable USER/PASS commands.
* STARTTLS now accepts a SSLv23 hello but doesn't allow SSLv23 to be
negotiated.
* imtest no longer buffers to aid use as an automated layer.
* master now supports maximum number of service processes via the
"maxchild" modifier.
* fixed a bug in the Sieve string lexer.
* one imapd process can now service multiple clients in sequence,
eliminating a large number of forks.
Changes to the Cyrus IMAP Server since 2.0.11
* portability fixes involving setrlimit()
* fixed compiler warnings
* the STARTTLS command will only accept TLSv1 now, not SSLv2/v3. The
imaps port is unaffected by this change.
* timsieved no longer returns garbage strings.
Changes to the Cyrus IMAP Server since 2.0.9
* some small memory savings
* the "fud" daemon once again works correctly
* the IDLE extension now uses signals correctly
* problems with libwrap have been resolved
* imapd and pop3d now log connections protected via TLS.
* efficiency improvements when searching for a particular message-id
* fixed an envelope-parsing bug affecting SORT and THREAD
* made RENAME keep the same mailbox uniqueid, preserving seen state
across renames
* STOREing flags to multiple messages in one command is now more
efficient
* RENAME now preserves the ACL
* LIST is now as efficient as Cyrus v1.6, modulo Berkeley DB issues.
* Sieve zephyr notifications are now correct.
* crash in reconstruct now fixed.
* man pages added for cyrus.conf, master, lmtpd, idled, ctl_mboxlist,
and ctl_deliver.

Changes to the Cyrus IMAP Server since 2.0.8
* remembered to update this file
* bug in Cyrus::IMAP perl module affecting cyradm's setquota fixed
* portability fix with socklen_t
Changes to the Cyrus IMAP Server since 2.0.7
* preliminary implementation of the IDLE extension (Ken Murchison,
ken@oceana.com).
* THREAD=REFERENCES now part of the normal build.
* tweaks to the installation documentation and suggested Sendmail
configuration
* portability fixes and other small bugfixes
* added "-a" flag to lmtpd
* master process can now export statistics about running processes
via UCD SNMP AgentX
* many fixes to Cyrus Murder-related code
* fixes to perl code, especially the Sieve interface. added an IMSP
interface to the perl code, but it still needs work.
Changes to the Cyrus IMAP Server since 2.0.6
* some number of random static variables eliminated, to save on
memory footprint
* recursive RENAME was a little to eager; fixed. RENAME will also
give the client a hint that a sub-RENAME failed. (mostly probably
useful for cyradm, but cyradm doesn't take advantage of it yet.)
* THREAD=X-JWZ has turned into THREAD=REFERENCES (Ken Murchison)
* DELETE wasn't failing cleanly in database code; fixed.
* off-by-one bug in seen_db fixed.
* starting/committing/aborting transactions now logged more correctly
in cyrsudb_db3
* master will now accept port numbers instead of just service names
in cyrus.conf. also logs even more verbosely (see bug #115.)
* libwrap_init() is now inside the loop, since i don't quite
understand the semantics of libwrap calls.
* setquota in cyradm now behaves more sanely (and gives correct usage
message).
* bugfixes to the managesieve client perl api. (still needs work.)
* small fixes in timsieved.
* added a "make dist" target so i won't dread releases as much.
Changes to the Cyrus IMAP Server since 2.0.5
* APPEND now honors the \Seen flag.
* mailboxes file can once again be a flat text file. (compile-time
choice)
* subscriptions file can be flat text or berkeley db. likewise for
seen state.
* unfortunately, the format of the mailboxes file has changed.
* implementation of "JWZ" threading, a first pass on the forthcoming
THREAD=REFERENCES.
* bugfixes in libacap.
* bugfixes in other Murder related functionality.
* removal of dead code.
* will now look in CYRUS_PREFIX/etc/imapd.conf if there's no
/etc/imapd.conf.
* more paranoid implementation of ID.
* more descriptive lmtp errors.
* finished implementation of LMTP 8BITMIME.
* fixed minor bugs in pop3d.
* small test suite for cyrusdb backends added in lib/test/.
* added -DPERL_POLLUTE to the perl compilation to deal with Perl 5.6.
* small additions to the Sieve library.
* As usual, owe lots of thanks to Ken Murchison for his hard work and
awesome implementations.
Changes to the Cyrus IMAP Server SINCE 2.0.4
* Now should work with Berkeley DB 3.1, but does not auto-upgrade 3.0
databases (and, in fact, I haven't written any upgrade software
yet).
* SORT and THREAD should now function correctly.
* Some configure fixes.
* Some fixes for possible race conditions in initializing services
and database structures.
* Some non-gcc compile fixes with structure initialization.
* Some non gcc compile fixes with structure initialization.
Changes to the Cyrus IMAP Server SINCE 2.0.3
* fixed mbpath and ipurge. Thanks to Alain Turbide for the bug
report.
* configure: removed mmap_private.c; it was buggy, and not worth
supporting.
* configure: improvements in detecting libwrap, typos fixed in
detecting libsasl.
* Merged the acapsieve library into libacap.
* improvements to the ACAP API.
* invariant checks added to the skiplist code.
* bugfix in TCL cyradm.
* acapmbox.c: bugfixes in handling acap connections.
* fix the size given for a unix socket address (changes throughout
the code), patch thanks to Vladimir Kravchenko, jimson@null.ru.
* rewrote deliver to use the generic LMTP API in lmtpengine.c.
Likewise, implemented the client-side API in lmtpengine.c. (Still
need to implement AUTH.)
* added SORT and THREAD support (Ken Murchison, ken@oceana.com.)
* In checking an APPEND command, we were rejecting valid system flags
and accepting invalid ones.
* minor bug fixes to proxyd.
* large amount of debugging code added to target-acap.
* build fixes to Perl programs.
* allow plaintext authentication to timsieved.
Changes to the Cyrus IMAP Server in 2.0
* The mailboxes file is now a transaction-protected Berkeley
database.
* The core delivery process has been moved to lmtpd. deliver is now a
simple wrapper to create an LMTP transaction.
* master process, responsible for spawning services (imapd, lmtpd,
etc.) and for routine housekeeping. Optionally, it can use libwrap
to allow or deny connections.
* ACAP (Application Configuration Access Protocol) support for Cyrus
Murder: IMAP Aggregator.
* Sieve enhancements: regular expressions, notifications,
automatically setting IMAP flags.
* SNMP (Simple Network Management Protocol) support for monitoring
usage (e.g. number of users logged in) as well as for instrumenting
protocol usage (e.g. number of times CREATE has been called).
* Perl version of cyradm contributed by Brandon Allbery
(allbery@ece.cmu.edu). Eventually we expect to transition to the
Perl version away from the TCL version.
* Bugfix in modified UTF-7 processing (for mailbox names). Bugfix in
index_searchcacheheader().
* Implemented the extension MULTIAPPEND.
* RENAME is now hierarchical.
* The right that controls whether a mailbox may be deleted is now
"c". (It used to be "d".)
* An additional backend for seen state has been created, seen_db. It
stores seen state in a per-user database.
Changes to the Cyrus IMAP Server Since Version 1.6.20
* Some fixes to the TLS support to gracefully degrade service.
* Sieve now correctly re-sieves messages that are received with
identical message-ids, but different envelopes. It also obeys
plus-addressing on keep actions. (Fixes by Ken Murchison,
ken@oceana.com.)
* The server wasn't correctly calculating the percentage of quota
used when deciding whether or not to issue a warning.
* Implemented single-instance store: deliver, when using LMTP, will
only store one copy of a message per partition, and hard link it
among multiple users. Sites with a large number of partitions could
see a performance decrease.
Changes to the Cyrus IMAP Server Since Version 1.6.19
* Added STARTTLS support; requires OpenSSL.
* Sieve now uses MDNs to reject messages instead of DSNs, conforming
to the latest Sieve specification. (Ken Murchison)
* The duplicate delivery database expiration (deliver -E) was
deleting all entries; fixed.
* imtest is now a little smarter about parsing the protocol to avoid
synchronization errors prior to authentication.
* timsieved's parser is now written in C; should be no noticeable
changes, but should make compiling it much easier.
Changes to the Cyrus IMAP Server Since Version 1.6.16
* Fix to enclosed message parsing (thanks to John Myers).
* When trying to skip over non-synchronizing literals during error
recovery, the IMAP server never stopped eating. Fixed.
* Added with-sasldir as a configure option.
* Fixed a bug in cyradm when it got the CAPABILITY list.
* Fixed bugs relating to the incomplete SASLfication of deliver.
* Fixed bugs in deliver relating to duplicate delivery suppression
and Sieve vacation functionality.
* Fixed a memory leak in deliver.
* When looking for SASL options, imapd wasn't defaulting to the
option without the plugin name requesting it. This caused PLAIN
authentications to incorrectly fail.
* Changed the expiration time of pts entries to 3 hours; only affects
sites using krb_pts as the authorization method.
* Fixed some bugs in imclient; mostly affects cyradm.
* Fixed a bug in the Sieve lexer and improved the usefulness of the
Sieve test program.
Changes to the Cyrus IMAP Server Since Version 1.6.13
* An annoying memory management bug in imclient was fixed and it's
efficiency was improved somewhat.
* Added the sieve client (installsieve) and server (timsieved) for
getting sieve scripts onto the server and managing them once they
are there.
* The default Sieve script layout has changed to
sievedir/u/user/default; this supports multiple Sieve scripts per
user with the ability to switch between them.
* Fixed the kerberos-to-local-host bug (patch by Greg Hudson,
ghudson@mit.edu).
* Started changes to deliver to support LMTP AUTH.
* Improved the error messages logged when authentication fails.
* Fixed a bug dealing with argument processing in the arbitron
program.
* pop3d now correctly supports SASL AUTH.
* imtest will no longer prompt for authentication or authorization
names; instead, it defaults to the current Unix user. Override on
the command line.
* Likewise, cyradm will no longer prompt. It now accepts "-m" to
specify what SASL mechanism to use, and the pwcommand option to
authenticate should once again work when used non-interactively.
Changes to the Cyrus IMAP Server Since Version 1.6.10
* Changed the sieve option in the configure script to
--disable-sieve.
* Updated reconstruct and quota to check for hashed imap spool
directories correctly.
* deliver now will not use Sieve if duplicate delivery suppression is
disabled. There was also a bug that caused the duplicate delivery
database to be checked even if dupelim was disabled.
* deliver now uses tm_gmtoff if available to check for the local
timezone.
* The default format for reading information from INN has changed. If
you use INN to feed imapd news, you must change your "newsfeeds"
file to contain
collectnews!:*:Tf,WO:collectnews
* The dohash script now takes a "-i" option to run interactively and
the "-f" option to issue warnings instead of fatal errors.
Changes to the Cyrus IMAP Server Since Version 1.6.1-BETA
* cyradm should now work with all mechanisms (it now handles empty
challenges and responses).
* Fixed deliver to deal with arbitrarily long headers
* COPY for non-existent sequence numbers returns NO; this contrasts
to UID COPY, which always returns OK.
* FETCH for non-existent sequence numbers returns NO; this contrasts
to UID FETCH, which always returns OK.
* Fixed a misleading BAD responses to commands that take sequences.
* Added UIDNEXT untagged response to a SELECT (from
draft-crispin-imapv-07.txt).
* pop3d now correctly passes SASL configuration options to libsasl.
* imtest now correctly flushes the server's output to the screen.
* Added more hashing using a simple but stupid algorithm. Now
whenever there is a mailbox access, quota access, or subscription
access, it goes through a hash function. this is done to help
reduce the number of files/directories in any given directory.
* Added the binary mbpath. Given a mailbox name, this binary will
print the filesystem path to that mailbox. This way if you have
multiple partitions and hashing turned out, you don't have to spend
as many mental cycles figuring out where the actual directory is.
* deliver now checks sieveusehomedir and sievedir in the config file
to determine where to look for sieve scripts.
* ptloader now has a workaround for afs 3.5.
* clarified an error message in message.c when an unexpected end of
file is encountered.
* fixed some random memory leaks in deliver.
* fixed a fairly major bug in prot_fill. it was performing
incorrectly when reading only a single character.
* fixed a bug in how imtest looked for OK or NO.
* fixed a memory leak in imapd.
* imapd now allows any user (or member of a group) listed in
"proxyservers" to proxy.
Changes to the Cyrus IMAP Server Since Version 1.6.0-BETA
* fixed stupid bug in imapd
* fixed sasl/config.c interaction
* fixed use of stat in imtest
Changes to the Cyrus IMAP Server Since Version 1.5.24
* ANSI C is now required.
* imtest's interface has changed, to allow for SASL authentication.
Sorry, but it had to happen. It now also includes a timing test
(-z) which we use to test the SASL layers.
* imtest no longer uses a non-synchronizing literal with LOGIN, so it
should work against all IMAP servers.
* The prot layer now uses SASL for encryption and authentication.
This changed a large amount of code, and some build procedures.
* As a side effect of SASL, --enable-static-libraries now doesn't do
anything. We are considering compiling cyrus with libtool to change
this.
* Error codes returned by programs have changed, and programs return
EX_TEMPFAIL far more than they used to. This is because Sendmail
considers most not-EX_TEMPFAIL errors permanent; now, if it may not
be permanent, EX_TEMPFAIL is returned. (See lib/exitcodes.h.)
* Two bugs fixed: UID FETCH's with no messages in range now return
OK, not BAD. And an obscure bug in LIST case sensitivity is fixed.
Changes to the Cyrus IMAP Server Since Version 1.5.19
* Most of the charset.c code (and mkchartable.c code) has been
replaced thanks to John Myers).
* Bug fix in message.c to look up headers in the cache when they're
in the cache correctly; thanks to Chris Newman for the fix.
* Code cleanup here and there (thanks to Bruce Balden).
* Annoying (and confusing) lines in syslog every time a message was
delivered if deliver was compiled using dbm saying that deliver was
"unable to fetch entry" have been removed.
* Content-Disposition lines were being parsed improperly. If they had
no optional arguments, they were being ignored as if they were
syntactically incorrect. This is fixed, but imapd will continue to
serve wrong information unless cyrus.caches are rebuilt (with
reconstruct) for any message that was added to the mailbox before
this bug was fixed.
* The arbitron program now takes a mailbox pattern argument for the
mailbox to run on. The manpage always said it did anyway.
* Uninitialized variable fixed in imapd.c with the shutdown file
code.
* Minor tweaks to purify build config.
* Fix minor memory leak in proc.c where procfname wasn't being
free'd.
* Fix brain fart in auth_krb_pts.c where a CLOSE() was done to a DB
handle BEFORE we access the data read from the DB database. This
means we were copying free'd memory into the groups list. Note this
only affects people using DB, AFS and ptloader.
* Committed minor syslog log level changes in ptloader and deliver.
* make distclean now does what it's supposed to.
* Possibly misnamed experimental --enable-static-libraries switch
that tries to do a good job of building binaries with whatever
static libraries are availible. If you use this, you do so at your
own risk, and if it fails, we will disavow all knowledge of you and
your team. Good luck, Jim.
* Add optional third argument to imtest for it to take input from a
file. This is a gross hack.
Changes to the Cyrus IMAP Server Since Version 1.5.14
* LIST now honors the reference argument.
This behavior can be turned off by a configuration option
imapd.conf--which may be desirable because of certain clients that
ask for a "mail directory" setting for IMAP which will now cause
problems when it was ignored before. (The default is for the
reference argument to be honored.)
* The arbitron program now takes a mailbox pattern argument for the
mailbox to run on. The manpage always said it did anyway.
* Added --disable-server switch to optionally prevent compilation of
server to help sites that just want client libraries (so cyradm and
libcyrus can be compiled on remote systems without installing stuff
into /usr/cyrus/bin, etc.) For now, the server is still configured
in this case, and a Makefile is generated. This could change in
future versions.
* Fixed a mmap leak in index.c in index_search_evaluate that caused
problems on complex searches. Thanks to Jeff Schiller for pointing
this out. Fixed a potential leak in mboxlist.c that happened if a
rename went awry. Thanks to Chris Newman for pointing this out.
* Fixed a bug in LIST and LSUB code so that user.* mailboxes will be
printed on every LIST instead of just the first one.
* Implemented the POP3 Extension Mechanism, RFC 2449, in order to
advertise the capabilities already supported.
* Fixed a bug in mailbox.c that disallowed MUTF-7 representations of
ASCII characters when it shouldn't have. (Thanks to John Myers for
providing a fix and to Per Steinar Iversen for telling me that I
didn't do it before.)
* More cleanup the ptloader/auth_krb_pts code. If you use Kerberos
and IMSP, you *MUST* pick up cyrus-imspd-v1.5a6 (or newer).
* A few configure tweaks.
* Duplicate delivery changes:
* Split out duplicate delivery elimination to multiple files.
This should help reduce the lock contention that normally
occurs with this file. To not clutter config_dir, the files
will be located in a subdirectory named deliverdb, for example
/var/imap/deliverdb. If you don't make this directory, nothing
bad will happen (other than duplicate delivery elimination will
not work).
* The time value is now stored as an integer in native byte order
as opposed to converting it to a string before it is stored in
the database.
* checkdelivered() now obtains a read lock instead of a write
lock when trying to check for duplicates. Only markdelivered()
grabs a write lock.
* Added logic to cause cyradm to abort more cleanly if not given
command line arguments in an interactive session. This gets rid of
the dreaded application-specific intialization failed messages.
Changes to the Cyrus IMAP Server Since Version 1.5.11
* The CREATE command now ignores a trailing hierarchy delimiter
instead of ignoring the CREATE command.
* UIDPLUS is now always advertised in CAPABILITY and is always
availible. The UIDPLUS extension is a set of optimizations using
UID values instead of sequence numbers and is described in RFC
2359.
* Cyrus no longer rejects messages with 8-bit characters in the
headers. Rather than reject the message, characters with the 8th
bit set are changed to 'X'. Internationalization in headers is
supported by the mechanism specified in RFC 2047 (and RFC 1342).
Changes to the Cyrus IMAP Server Since Version 1.5.10
* If ENABLE_EXPERIMENT is set, the server no longer claims to support
OPTIMIZE-1; instead, it claims to support UIDPLUS. The Getuids
command has been removed since it is not in the UIDPLUS document
(draft-myers-imap-optimize-03.txt).
* The checks for Tcl in configure are much smarter. The configure
script asks tclsh where its configuration lives, then consults the
shell scripts that have that information. This should work with 7.5
or better, which is what the server requires anyway. (All the
previous checks to look for Tcl libraries are gone; now, configure
runs tclsh and asks it where the Tcl libraries are, then runs the
shell scripts that are in that directory. Since the tclConfig.sh
script may not be in that directory, it looks in .. as well.)
* The checks for com_err in configure are a little smarter and look
to see if all the pieces are there before trying to use them.
* Added support for the NAMESPACE extension (if --enable-experiment
is supplied).
* Added a "reject8bit" switch to imapd.conf. If set to "true",
messages containing 8-bit-set characters in the headers are
rejected (the previous behavior); if set to "false" or left to the
default value, messages containing 8-bit-set characters have these
characters changed to a constant character ('X').
* Added the "fud" program. This is an interm hack designed to allow
allow finger information to be retrieved for cyrus users. This is
experimental and it is not recommend that services be built arround
this feature, since it is likely to be removed in a future release
of the IMAP server.
* Bug fix: User defined flags now work properly.
Changes to the Cyrus IMAP Server Since Version 1.5.2
* Fixed a bug with word alignment on Solaris using Kerberos compiled
with Sun's CC. (Several patches were submitted; thanks to everyone
who did so.)
* Patches from John Myers, including more glob fixes.
* Use the default hash function from DB. Note that this means that
the existing delivered.db and ptscache.db is NOT compatible with
this release. These files should be removed.
* Provide two debugging programs that dump the databases: ptdump and
dump_deliverdb.
* Multiple changes to ptloader. added a bunch of flags; let it
reauthenticate on its own; added support perl wrapper; added bunch
of debugging information/output; bunch of other cleanups
* The mailboxes file is now closed if it isn't likely to be
referenced, hopefully preventing old mailboxes files from hanging
around in memory as frequently.
* Added a patch from Eric Hagberg to work around a possible deadlock
condition in mboxlist.c where rename isn't atomic.
* Patch from John Myers to get rid of cyrus.seen corruption in
bsearch_mem.
* Patch from John Myers and to allow ISO-8859-1 characters in mailbox
names.
* Makedepend still runs, and still generates warnings, but these are
squirrled away in makedepend.log.
* On mailbox delete, the server will no longer try and unlink ".."
and "." as we got a report that it seriously breaks one file system
(even as non-root).
* Added some support for Netscape's very misleading "Administrate My
Mail" menu option in Communicator. Allows for a URL to be set in
imapd.conf for the page to refer users to; needs to be turned on
with --enable-netscapehack at compile time to enable it.
* Bug swap: imtest quotes password with a non-synchronizing literal
in order to allow weird characters like ) in passwords. But it
doesn't look to see if the server supports non-synchronizing
literals.
* If the file "msg/motd" exists, the first line is now sent to
clients upon login.
* Bug fix: to handle BODY[] properly when fetching news articles
(truncation no longer occurs). (thanks to John Prevost)
* The makedepend supplied should now run on Solaris Intel. (thanks to
Chris Newman)
* Added some hacks to pwcheck.c for Linux and Digital Unix where the
default protections on the socket don't allow the cyrus user to
read it. (thanks to Lyndon Nerenberg)
* Bug fix: Flags beginning with \ are system flags and users can only
create the defined flags. The code to do this before was confused.
* The configure scripts and makefiles have some random fixes.
* Added a contrib directory for reasons of laziness in collecting
patches, not all of which should be in the distribution.
* ptloader can now renew its AFS authentication by reading from a
srvtab file.
* The configure script now looks for a libcom_err and can use an
installed one if one exists.
* Other small bug fixes.
Changes to the Cyrus IMAP Server Since Version 1.5
* Bug fix: RENAME corrupted mailboxes if they had been EXPUNGEd. (may
have only happened with INBOX, which Pine tickles once a month.)
* Bug fix: auth_newstate now initializes its structures.
* Bug fix: pop3d.c, a printf was changed to prot_printf.
* Cyrus now sends X-NON-HIERARCHICAL-RENAME to alert clients that it
is not handling RENAME in an IMAP4rev1 compliant manner. This will
be fixed in a subsequent release.
* Bug fix: imclient_autenticate now does resolution on the hostname
before authenticating to it. This caused problems when
authenticating to an address that was a CNAME.
* Bug fix: LIST %.% (and other multiple hierarchy delimiter matches)
works properly. Several other glob.c fixes are included as well.
* Bug fix: a fetch of exclusively BODY[HEADER.FIELDS...] should now
work properly.
* Bug fix: reconstruct now considers a nonexistant INN news directory
to be empty; this makes reconstruct fix the cyrus.* files in the
imap news partition.
* Added a manpage for imclient.
* Fixed a few other minor bugs.
Changes to the Cyrus IMAP Server Since Version 1.4
* Implemented the "IMAP4rev1" protocol commands. (The hierarchical
behavior of RENAME, which was added late to the IMAP4rev1
specification, is not implemented.) Changes the minor version
number of the cyrus mailbox database format to 1. IMPORTANT: it is
necessary to run the command "reconstruct -r" as the cyrus user
after upgrading the Cyrus IMAP software from version 1.4 or
earlier.
* If the file "msg/shutdown" exits in the configuration directory,
the IMAP server will issue the first line in the file in an
untagged BYE message and shut down.
* Permit SPACE in mailbox names.
* Permit the "modified UTF-7" internationalized mailbox name
convention.
* "User opened mailbox" messages are now logged at the DEBUG level
instead of the INFO level.
* Added -q (ignore quota) switch to deliver.
* New "krbck" program for diagnosing common kerberos problems.
* auth_unix no longer requires users to be in the passwd file.
* AUTHENTICATE command now reports the protection mechanism in use in
the text of the tagged OK response
* Make MAILBOX_BADFORMAT and MAILBOX_NOTSUPPORTED temporary errors.
* Use the header cache for SEARCH HEADER
* Use "unspecified-domain" instead of server's hostname to fill out
RFC 822 addresses without the "@domain" part.
* Make "reconstruct -r" with no args reconstruct every mailbox.
* The configure script now defaults to using unix_pwcheck instead of
unix if the file /etc/shadow exists.
* The location of the pwcheck socket directory now defaults to
"/var/ptclient/". It is controlled by the "--with-statedir=DIR"
option, which defaults to "/var".
* Bug fix: by using an certain address form, one could deliver to a
user's mailbox bypassing the ACL's.
* Bug fix: un-fold header lines when parsing for the ENVELOPE.
* Delete quota roots when deleting the last mailbox that uses them.
Doesn't catch all cases, but should get over 99% of them.
* Implement plaintextloginpause configuration option, imposes
artificial delay on plaintext password logins.
* Implement popminpoll configuration option, limits frequency of POP3
logins.
* Implement AFS PT server group support.
* Remove persistence of POP3 LAST value and remove Status: hack
* Support the new ACL command set in the IMAP server.
* Bug fix: Have to initialize reply to 0 in pop3d. Was causing POP3
server to occasionally drop the connection during authentication.
* Bug fix: The COPY command wasn't issuing a [TRYCREATE] when
appropriate for sub-mailboxes of INBOX.
* Bug fix: Renaming a mailbox wasn't correctly changing its
UIDVALIDITY.
* Bug fix: Renaming a mailbox to itself, in order to move it to a
different partition, was not working correctly.
* Update the AUTH support in pop3d to conform to the latest draft
specification.
* Update cyradm to use Tcl 7.5 instead of Tcl 7.4
* Re-implement large sections of the netnews support. It no longer
requires modifications to INN, as it now expunges the index entries
for expired/canceled articles upon select of the newsgroup.
* Implement newsspool configuration option, for separating the
directories for the news spool and the various cyrus.* IMAP server
index files.
* Bug fix: permit empty flag list in APPEND command
* Bug fix: deal with truncated Date: header values.
* Bug fix: memory mapping code, deal better with 0-length maps, since
mmap() appears to crap out on that boundary condition.
* Portability fix: if no strerror, have to define NEED_SYS_ERRLIST.
* Bug fix: used append instead of lappend in cyradmin, preventing use
of any port other than IMAP.
* When the client is streaming its commands, the IMAP server attempts
to stream its tagged responses.
* Modify zephyr support to compile without Kerberos support.
* Add a bunch of prototype declararations to the code.
* In deliver, change the MULT support to instead use the LMTP syntax.
* imclient: support tagged intermediate replies and a default
callback.
* Implement some experimental protocol extensions for optimizing
disconnected use resynchronization. Most extensions are disabled by
default. Client authors should contact info-cyrus@andrew.cmu.edu if
they wish to experiment with these.
* In Makefiles, change $(AR) to ar -- HPUX make is defective.
* In deliver, use HAVE_LIBDB to select use of db over dbm
* Add map_stupidshared mapping module for older versions of Digital
Unix. It's not quite as bad as HPUX, but...
* Bug fix: in imclient.c, don't free NULL pointers and don't call
htons() on the output of getservbyname(). Have to abort sending the
command if you get a tagged response when sending a literal.
* The auth_xxx routines now create/take a state argument instead of
maintaining internal static state.
* Solaris mktime() is buggy in some releases. Create and use
mkgmtime() for parsing date strings.
* Message parsing routines now use memory mapping, though they still
copy data around in line-sized buffers.
Changes to the Cyrus IMAP Server Since Version 1.3
* Implemented the "reconstruct -m" command, for reconstructing the
mailboxes file. IMPORTANT: it is necessary to run the command
"reconstruct -m" as the cyrus user after upgrading the Cyrus IMAP
software from version 1.3 or earlier. We recommend you make a
backup copy of the mailboxes file in the configuration directory
before performing the conversion.
* Mailbox names are now case sensitive, not case insensitive. "INBOX"
is the exception, and is treated as being case-insensitive.
* Personal mailboxes now appear to their owners as being under the
"INBOX." hierarchy. For example, the mailbox "user.bovik.work"
appears to the user "bovik" as "INBOX.work". The user may still
refer to the mailbox with the name "user.bovik.work".
* Previously, the code used "anybody" as the name of the group that
all users are in, but the documentation used the name "anyone".
Changed the code to match the documentation. The name "anybody"
will be canonicalized to the name "anyone".
* The install document now gives different recommended locations for
the server databases. The recommended location of the configuration
directory changed from "/usr/cyrus" to "/var/imap" and the
recommended location of the default partition directory changed
from "/usr/spool/cyrus" to "/var/spool/imap". It is NOT necessary
to change the locations of these directories when upgrading from
version 1.3 or earlier of the Cyrus IMAP server software. If you do
wish to change the locations of these directories to match the new
recommendations, simply rename the directories and change the
appropriate values in your /etc/imapd.conf file.
* Created a "make install" rule. See the installation document for
all the new corresponding configure options. Note the recommended
location of the "imapd", "pop3d", and "deliver" programs has
changed, this change needs to be reflected in the "inetd.conf" and
"sendmail.cf" files.
* New "login_unix_pwcheck" module and "pwcheck" daemon, for improved
shadow password support. See the "pwcheck/README.pwcheck" file in
the distribution for details.
* Renamed the "login_unix_shadow" module to "login_unix_getspnam".
* Added a mail notification mechanism, using Zephyr.
* Added a feature to automatically create user IMAP accounts.
Controlled by the "autocreatequota" config option.
* Added the "logtimestamps" config option, for putting timestamp
information into protocol telemetry logs.
* Beefed up the Kerberos checks in Configure to ensure the DES
library routines exist.
* On some systems, the "echo" command with no arguments emits a
newline. Changed the installation document to instead use the
"true" command to create the "mailboxes" file.
* Store a redundant copy of a mailbox's ACL in the cyrus.header file,
so "reconstruct -m" may later use it as a backup.
* Had to remove the declaration of tcl_RcFileName for the latest
version of Tcl.
* Make much more extensive use of memory mapping. Replace the binary
search module with one that searches a memory mapped area.
* Replaced the yacc-based RFC822 address parser with a hand-coded
one.
* Replaced the et (error table) libary with a version that doesn't
require lex or yacc. Remove the lex/yacc checking from Configure.
* Safety feature: most programs now refuse to run as root.
* Bug fix: Issue [TRYCREATE] tag on COPY command when appropriate.
* Bug fix: The quoted-printable decoder wasn't ignoring trailing
whitespace, as required by MIME.
* Bug fix: Don't spew cascade errors if the server gets an EOF
during/after reading an APPEND literal.
* Bug fix: gmtmoff_gmtime.c was returning results with the wrong
sign.
* Bug fix: imclient_send was appending spaces to %d and %u and the
response parser was not handling responses that did not contain a
space after the keyword.
* Bug fix: rmnews wasn't removing some (un-indexed) article files
correctly.
* Completely disabled the dropoff code for now. It will be completely
replaced when IMSP integration is implemented
* Added workaround for the Linux mkdir() problem.
* In Configure, use a more direct test for a working shared-memory
mmap
* In collectnews, avoid O(n**2) behavior when processing articles
that have already expired.
* Bug fix: append_addseen() would screw up if no messages were
previously seen.
* Added the CMU-specific amssync and cmulocal directories.
* Use memmove instead of bcopy.
* Implemented the first pass of SMTP/MULT support in deliver.
* Added cacheid parameter to auth_setid(), for AFS PT server support.
Changes to the Cyrus IMAP Server Since Version 1.2
* Fixed bug in character set code that broke text searches. Sites
which care about searching headers need to reconstruct their
existing mailboxes.
Changes to the Cyrus IMAP Server Since Version 1.1-Beta
* Add support for UIDVALIDITY special information token.
* Add syncnews and arbitron programs.
* Redo duplicate delivery elimination in deliver.
* Bug fixed: Must re-read files after acquiring a lock. Cannot trust
the mtime of a file to increment when writing the file--file could
be written to multiple times in the same second.
* Bug fixed: EXAMINE command should not affect \Recent status.
* Update the user's \Recent high-water-mark when we report new
messages.
* Portability changes
* Upgrade to autoconf 2.1
* Allow privacy to be turned off at compile-time with
--disable-privacy configure switch.
* Fix typo in cyradm preventing "all" from being recognized.
* Include map_private.c memory mapping module for systems like HPUX
which have half-working mmap() implementations.
* Switch to using UTF-8 for internal search format. Sites which care
about internationalized searching of headers need to reconstruct
all their existing mailboxes.
* Fix some errors in the iso-8859-* tables.
* Add and correct a bunch of case-independence mappings in the
character tables.
* First pass at implementing the STATUS extension; disabled for
release.
* First pass at implementing IMAP/IMSP server integration. Not ready
for general use.
* Add new_cred and free_cred mechanisms to authentication modules.
* Don't complain when doing "reconstruct -r foo" and foo isn't a
mailbox.
* Add IMAP_QUOTAROOT_NONEXISTENT error code.
* Bug fix: Avoid divide by zero when quota is zero
* Bug fix: In an error case of the ACL handling code, we have to
restore tab before breaking out of loop.
* Fix file descriptor leak in quota system.
* Change a bunch of int variables to unsigned.
* Better error reporting on reads that end up short.
Changes to the Cyrus IMAP Server Since Version 1.0-Beta
* Improved installation document.
* New "cyradm" administrative client.
* Changed the syslog facility from "local4" to "local6".
* Removed the renounce setuid check in "deliver". The "deliver"
program must now be non-executable by other.
* Fixed a typo in the parsing of SEARCH DELETED. (This bug constantly
got tripped by newer C-clients.)
* Redesigned the implementation of SEARCH CHARSET.
Sites that wish to search for non-ASCII characters in the headers
of existing mailboxes must run reconstruct on all their mailboxes
after upgrading to this version.
* Added AUTH and KPOP support to the POP3 server.
* Added search support for the ISO-2022-JP character set.
* Replaced the search engine with a partial Boyer-Moore algorithm.
* Special-case optimized searching US-ASCII text.
* Fixed a bug which caused the message parser to spin-loop on a
particular degenerate invalid-MIME case.
* Fixed a performance bug in the message parser.
* Tracked last-minute changes to the IMAP4 protocol.
* Fixed a bug in UNSUBSCRIBE which caused too many subscriptions to
be removed.
* Added a bunch more "configure" options.
* Ported to HPUX.
* Fixed a bug in the LIST/LSUB \Noselect code.
* Fixed bug in the globbing code which caused the "*%" pattern to
work incorrectly.
* Client-side Kerberos support is now conditionalized on
HAVE_ACTE_KRB, which is set by configure.
* Fixed some invalid buffer-alignment assumptions in the Kerberos
code.
* Made the lexers compatible with flex. Configure now looks for and
prefers to use flex and bison/byacc.
* Made the IMAP server check for the existence of the mailboxes file
upon startup, in order to give a more informative error message for
this common configuration error.
* Fixed other minor bugs.
