<li>Fixed COPY code so that clients display new messages (added MODSEQ).</li>
<li>Fixed imtest to be compatible with SASL 2.1.22.</li>

<h1>Changes to the Cyrus IMAP Server since 2.3.4</h1> 
<li>Fixed append/delivery code so that clients display new messages.</li>

<h1>Changes to the Cyrus IMAP Server since 2.3.3</h1> 
<li>Added support for BINARY APPEND (including CATENATE).

IMAP/POP3/NNTP traffic.</li>
<li>Properly handle timeouts when proxying.</li>
<li>Added plaintextloginalert option.</li>
<li>Fixed segfault in deliver.</li>
<li>Only allow mbpath to be run as Cyrus user.</li>

<li>Updated ACL code to RFC 4314 (separate rights for message delete,
mailbox delete, and expunge).</li>
<li>Fixed IDLE to use idled for local mailboxes.</li>
<li>Fixed miscellaneous build issues.</li>

<h1>Changes to the Cyrus IMAP Server since 2.2.x</h1>
<li>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 <tt>proxyd</tt> and <tt>lmtpproxyd</tt> has been
merged with <tt>imapd</tt> and <tt>lmtpd</tt> respectively), or all
"replicated" servers can serve the same mailboxes from a shared
filesystem.  The new <tt>mupdate_config</tt> option in
<tt>imapd.conf</tt> is used to determine whether a Murder is using a
"traditional", "unified" or "replicated" configuration.</li> 
<li>Ported/rewrote/integrated David Carter's mailspool replication
code.  <i>Development sponsored by Columbia University</i>.</li>
<li>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 <tt>cyr_expire</tt>.  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 <tt>expunge_mode</tt>
option in <tt>imapd.conf</tt> controls whether expunges are
"immediate" or "delayed".  <i>Development sponsored by FastMail</i>.</li>
<li>Added support to place some/all mailbox metadata files (cyrus.*
files) on a separate (probably high-speed) partition.  See the new
<tt>metapartition</tt> and <tt>metapartition_files</tt> options for
details.  <i>Development sponsored by FastMail</i>.</li>
<li>Added support for accessing subfolders of INBOX via POP3.  See the
new <tt>popsubfolders</tt> option for details.  <i>Development
sponsored by FastMail</i>.</li>
<li>Added support to <tt>lmtpd</tt> to do "fuzzy" mailbox matching
on user+detail addresses.  See the new
<tt>lmtp_fuzzy_mailbox_match</tt> option for details.  <i>Development
sponsored by FastMail</i>.</li>
<li>Added new <tt>sieve_extensions</tt> option to allow individual
Sieve extensions to be enabled/disabled.</li>
<li>The Sieve "include" extension is now supported.  This also allows
for global sieve scripts.  See the new <tt>sieve_extensions</tt>
options to enable it.</li>
<li>The Sieve "body" extension is now supported.  See the new
<tt>sieve_extensions</tt> option to enable it.  <i>Development
sponsored by FastMail</i>.</li>
<li>The $text$ variable for Sieve notify messages is now supported.
<i>Development sponsored by FastMail</i>.</li>
<li>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.  <i>Development sponsored by
<li>Support 64-bit quota usage (both per mailbox and for the entire
quotaroot), based on a patch from Jeremy Rumpf.  <i>Development
sponsored by FastMail</i>.</li>
<li>Added new <tt>flushseenstate</tt> 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.  <i>Based on a patch by John A. Tamplin
<li>The Sieve "copy" extension is now supported.</li>
<li>The IMAP "CATENATE" and "URLAUTH" extensions are now supported.</li>
<li>Updated Sieve "vacation" extension to draft-ietf-sieve-vacation-04.</li>
<li>Added support for Sieve scripts on shared mailboxes via the 
/vendor/cmu/cyrus-imapd/sieve annotation.</li>

<h1>Changes to the Cyrus IMAP Server since 2.2.13</h1> 
<li><tt>ctl_mboxlist</tt> now dumps/undumps the mailbox type flags,
making it useful for remote mailboxes.</li>

fixed, including issues with the Murder, and with Sieve.</li>

<h1>Changes to the Cyrus IMAP Server since 2.1.x</h1>

<li>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:
  <li> 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.</li>
  <li> Administrative groups (e.g. admins and lmtp_admins) no longer union,
service groups completely override the generic group. </li>
  <li> 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</li>

<li> 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 </li>

<li> Virtual domain support.  See the <a
href="install-virtdomains.html">virtual domains</a> document for

<li> 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 <tt>allowusermoves</tt> option in
<tt>imapd.conf(5)</tt> for details.</li>

<li> The <tt>db3</tt> and <tt>db3-nosync</tt> database backends have
been renamed to <tt>berkeley</tt> and <tt>berkeley-nosync</tt>
respectively (to avoid confusion over whether or not db4 is supported).</li>

<li> The default mailbox list and seen state database formats have changed
to skiplist from Berkeley and Flat, respectively. </li>

<li> ptloader is now a regular cyrus service.  This has several implications,
see <a href=install-upgrade.html>install-upgrade.html</a> for more details.</li>

<li> 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 <a
href="install-netnews.html">netnews</a> document for details.</li>

<li>IPv6 support, provided by Hajimu UMEMOTO &lt;;</li>

<li> Sieve scripts are now compiled to bytecode to allow for faster
execution (and lmtpd no longer needs lex or yacc).  See
<a href=install-upgrade.html>install-upgrade.html</a> for more details.</li>

<li> The functionality of pop3proxyd has been merged into pop3d.  Be
sure to update <tt>cyrus.conf</tt> on your frontend machines accordingly.</li>

<li> The functionality of <tt>ctl_deliver -E</tt> has been moved to
<tt>cyr_expire -E</tt>.  Be sure to update <tt>cyrus.conf</tt> on your
machines accordingly.</li>

<h2>Changes to the Cyrus IMAP Server since 2.1.4</h2>


<li> Sieve is no longer dependent on duplicate delivery suppression
(it still uses the duplicate delivery database however). </li>

<li> Sieve now supports <tt>draft-segmuller-sieve-relation-02.txt</tt></li>

<li> <tt>imtest</tt> 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.  <tt>imtest</tt> 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).</li> 

<li>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.</li>

<li>Added the chk_cyrus program to help point out missing message
files and/or mailboxes</li>

<li>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)</li>

<li>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.  <tt>ctl_cyrusdb -r</tt> now also
cleans up "reserved" mailboxes that may appear in the event of a crash.</li>

<li><tt>ctl_mboxlist</tt> can now dump only a particular partition</li>

<li>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.</li>

<li>Many bugfixes related to the Cyrus Murder.  Includes improvments to
subscription handling as well as correct merging of seen state on
mailbox moves.</li>

<li>Can now configure an external debugger (<tt>debug_command</tt> option

<h2>Changes to the Cyrus IMAP Server since 2.1.3</h2>

<li> All "MAIL" and "SIEVE" notifications are now handled by
<tt>notifyd</tt> which is a daemon that supports multiple notification
methods.  The <tt>mailnotifier</tt> and <tt>sievenotifier</tt> options
have been added to <tt>/etc/imapd.conf</tt> to configure
notifications. (Ken Murchison) </li>

<li> 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. </li>

<li> Some warning fixes. </li>

<li> <tt>fdatasync()</tt> is no longer required. </li>

<li> Fixed a bug in <tt>imap/append.c</tt> that would show itself if a
message was being delivered to five or more different
partitions. </li>

<li> Deliveries now don't create a redudant temporary file using
<tt>tmpfile()</tt>; the staging directory is used instead. (Ken
Murchison) </li>

Murchison) </li>

<li> Deleting a user now also removes their Sieve scripts. </li>

<li> <tt>cyrusdb_skiplist</tt>: release locks during iteration.
Should prevent denial of service attacks and possibly increase
performance. </li>

<li> <tt>cyrusdb_skiplist</tt>: introduce a new mode using
<tt>O_DSYNC</tt> writes which is possibly faster on Solaris.
Currently off (it seems to hurt performance on Linux). </li>

<li> <tt>master</tt> has preliminary code to avoid forking
storms. </li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.6.20</h2>

<li>Some fixes to the TLS support to gracefully degrade

<li>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,

<li>The server wasn't correctly calculating the percentage of quota
used when deciding whether or not to issue a warning.</li>

<li>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.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.6.19</h2>

<li>Added STARTTLS support; requires OpenSSL.</li>

<li>Sieve now uses MDNs to reject messages instead of DSNs,
conforming to the latest Sieve specification. (Ken Murchison)</li>

<li>The duplicate delivery database expiration (deliver -E) was
deleting all entries; fixed.</li>

<li>imtest is now a little smarter about parsing the protocol to
avoid synchronization errors prior to authentication.</li>

<li>timsieved's parser is now written in C; should be no noticeable
changes, but should make compiling it much easier.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.6.16</h2>

<li>Fix to enclosed message parsing (thanks to John Myers).</li>

<li>When trying to skip over non-synchronizing literals during
error recovery, the IMAP server never stopped eating. Fixed.</li>

<li>Added <tt>with-sasldir</tt> as a configure option.</li>

<li>Fixed a bug in cyradm when it got the CAPABILITY list.</li>

<li>Fixed bugs relating to the incomplete SASLfication of

<li>Fixed bugs in deliver relating to duplicate delivery
suppression and Sieve vacation functionality.</li>

<li>Fixed a memory leak in deliver.</li>

<li>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.</li>

<li>Changed the expiration time of pts entries to 3 hours; only
affects sites using krb_pts as the authorization method.</li>

<li>Fixed some bugs in imclient; mostly affects cyradm.</li>

<li>Fixed a bug in the Sieve lexer and improved the usefulness of
the Sieve test program.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.6.13</h2>

<li>An annoying memory management bug in imclient was fixed and
it's efficiency was improved somewhat.</li>

<li>Added the sieve client (<tt>installsieve</tt>) and server
(<tt>timsieved</tt>) for getting sieve scripts onto the server and
managing them once they are there.</li>

<li>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.</li>

<li>Fixed the kerberos-to-local-host bug (patch by Greg Hudson,

<li>Started changes to deliver to support LMTP AUTH.</li>

<li>Improved the error messages logged when authentication

<li>Fixed a bug dealing with argument processing in the arbitron

<li>pop3d now correctly supports SASL AUTH.</li>

<li>imtest will no longer prompt for authentication or
authorization names; instead, it defaults to the current Unix user.
Override on the command line.</li>

<li>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

<h2>Changes to the Cyrus IMAP Server Since Version 1.6.10</h2>

<li>Changed the sieve option in the configure script to

directories correctly.</li>

<li>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

<li>The default format for reading information from INN has
changed. If you use INN to feed imapd news, you must change your

<li>The dohash script now takes a "<tt>-i</tt>" option to run
interactively and the "<tt>-f</tt>" option to issue warnings
instead of fatal errors.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.6.1-BETA</h2>

<li>cyradm should now work with all mechanisms (it now handles
empty challenges and responses).</li>

<li>Fixed deliver to deal with arbitrarily long headers</li>

<li>COPY for non-existent sequence numbers returns NO; this
contrasts to UID COPY, which always returns OK.</li>

<li>FETCH for non-existent sequence numbers returns NO; this
contrasts to UID FETCH, which always returns OK.</li>

<li>Fixed a misleading BAD responses to commands that take

<li>Added UIDNEXT untagged response to a SELECT (from

<li>pop3d now correctly passes SASL configuration options to

<li>imtest now correctly flushes the server's output to the

<li>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.</li>

<li>Added the binary <tt>mbpath</tt>. 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.</li>

<li>deliver now checks <tt>sieveusehomedir</tt> and
<tt>sievedir</tt> in the config file to determine where to look for
sieve scripts.</li>

<li>ptloader now has a workaround for afs 3.5.</li>

<li>clarified an error message in message.c when an unexpected end
of file is encountered.</li>

<li>fixed some random memory leaks in deliver.</li>

<li>fixed a fairly major bug in prot_fill. it was performing
incorrectly when reading only a single character.</li>

<li>fixed a bug in how imtest looked for OK or NO.</li>

<li>fixed a memory leak in imapd.</li>

<li>imapd now allows any user (or member of a group) listed in
"proxyservers" to proxy.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.6.0-BETA</h2>

<li>fixed sasl/config.c interaction</li>

<li>fixed use of stat in imtest</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.5.24</h2>

<li>ANSI C is now required.</li>

<li>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.</li>

<li>imtest no longer uses a non-synchronizing literal with LOGIN,
so it should work against all IMAP servers.</li>

<li>The prot layer now uses SASL for encryption and authentication.
This changed a large amount of code, and some build

<li>As a side effect of SASL, --enable-static-libraries now doesn't
do anything. We are considering compiling cyrus with libtool to
change this.</li>

<li>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

<li>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

<h2>Changes to the Cyrus IMAP Server Since Version 1.5.19</h2>

<li>Most of the charset.c code (and mkchartable.c code) has been
replaced thanks to John Myers).</li>

<li>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

<li>Code cleanup here and there (thanks to Bruce Balden).</li>

<li>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.</li>

<li>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.</li>

<li>The arbitron program now takes a mailbox pattern argument for
the mailbox to run on. The manpage always said it did anyway.</li>

<li>Uninitialized variable fixed in imapd.c with the shutdown file

<li>Minor tweaks to purify build config.</li>

<li>Fix minor memory leak in proc.c where procfname wasn't being

<li>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.</li>

<li>Committed minor syslog log level changes in ptloader and

<li>make distclean now does what it's supposed to.</li>

<li>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.</li>

<li>Add optional third argument to imtest for it to take input from
a file. This is a gross hack.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.5.14</h2>

<li>LIST now honors the reference argument. 

<p>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.)</p>

<li>The <tt>arbitron</tt> program now takes a mailbox pattern
argument for the mailbox to run on. The manpage always said it did

<li>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.</li>

<li>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.</li>

<li>Fixed a bug in LIST and LSUB code so that user.* mailboxes will
be printed on every LIST instead of just the first one.</li>

<li>Implemented the <i>POP3 Extension Mechanism</i>, RFC 2449, in
order to advertise the capabilities already supported.</li>

<li>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.)</li>

<li>More cleanup the ptloader/auth_krb_pts code. If you use
Kerberos and IMSP, you *MUST* pick up cyrus-imspd-v1.5a6 (or

<li>A few configure tweaks.</li>

<li>Duplicate delivery changes: 

<li>Split out duplicate delivery elimination to multiple files.
This should help reduce the lock contention that normally occurs
with this file. To not clutter <i>config_dir</i>, the files will be
located in a subdirectory named <tt>deliverdb</tt>, for example
<tt>/var/imap/deliverdb</tt>. If you don't make this directory,
nothing bad will happen (other than duplicate delivery elimination
will not work).</li>

<li>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

<li>checkdelivered() now obtains a read lock instead of a write
lock when trying to check for duplicates. Only markdelivered()
grabs a write lock.</li>

<li>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 <tt>application-specific intialization failed</tt>

<h2>Changes to the Cyrus IMAP Server Since Version 1.5.11</h2>

<li>The CREATE command now ignores a trailing hierarchy delimiter
instead of ignoring the CREATE command.</li>

<li>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

<li>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

<h2>Changes to the Cyrus IMAP Server Since Version 1.5.10</h2>

<li>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).</li>

<li>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
script may not be in that directory, it looks in .. as well.)</li>

<li>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

<li>Added support for the NAMESPACE extension (if
--enable-experiment is supplied).</li>

<li>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').</li>

<li>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.</li>

<li>Bug fix: User defined flags now work properly.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.5.2</h2>

<li>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.)</li>

<li>Patches from John Myers, including more glob fixes.</li>

<li>Use the default hash function from DB. Note that this means
that the existing <tt>delivered.db</tt> and <tt>ptscache.db</tt> is
<b>NOT</b> compatible with this release. These files should be

<li>Provide two debugging programs that dump the databases:
<tt>ptdump</tt> and <tt>dump_deliverdb</tt>.</li>

<li>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</li>

<li>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.</li>

<li>Added a patch from Eric Hagberg to work around a possible
deadlock condition in mboxlist.c where rename isn't atomic.</li>

<li>Patch from John Myers to get rid of cyrus.seen corruption in

<li>Patch from John Myers and to allow ISO-8859-1 characters in
mailbox names.</li>

<li>Makedepend still runs, and still generates warnings, but these
are squirrled away in makedepend.log.</li>

<li>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).</li>

<li>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.</li>

<li>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

<li>If the file "<tt>msg/motd</tt>" exists, the first line is now
sent to clients upon login.</li>

<li>Bug fix: to handle BODY[] properly when fetching news articles
(truncation no longer occurs). (thanks to John Prevost)</li>

<li>The makedepend supplied should now run on Solaris Intel.
(thanks to Chris Newman)</li>

<li>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)</li>

<li>Bug fix: Flags beginning with \ are system flags and users can
only create the defined flags. The code to do this before was

<li>The configure scripts and makefiles have some random

<li>Added a contrib directory for reasons of laziness in collecting
patches, not all of which should be in the distribution.</li>

<li>ptloader can now renew its AFS authentication by reading from a
srvtab file.</li>

<li>The configure script now looks for a libcom_err and can use an
installed one if one exists.</li>

<li>Other small bug fixes.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.5</h2>

<li>Bug fix: RENAME corrupted mailboxes if they had been EXPUNGEd.
(may have only happened with INBOX, which Pine tickles once a

<li>Bug fix: auth_newstate now initializes its structures.</li>

<li>Bug fix: pop3d.c, a printf was changed to prot_printf.</li>

<li>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.</li>

<li>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.</li>

<li>Bug fix: LIST %.% (and other multiple hierarchy delimiter
matches) works properly. Several other glob.c fixes are included as

<li>Bug fix: a fetch of exclusively BODY[HEADER.FIELDS...] should
now work properly.</li>

<li>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.</li>

<li>Added a manpage for imclient.</li>

<li>Fixed a few other minor bugs.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.4</h2>

<li>Implemented the "<tt>IMAP4rev1</tt>" 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.
<b>IMPORTANT:</b> it is necessary to run the command
"<tt>reconstruct -r</tt>" as the cyrus user after upgrading the
Cyrus IMAP software from version 1.4 or earlier.</li>

<li>If the file "<tt>msg/shutdown</tt>" exits in the configuration
directory, the IMAP server will issue the first line in the file in
an untagged BYE message and shut down.</li>

<li>Permit SPACE in mailbox names.</li>

<li>Permit the "modified UTF-7" internationalized mailbox name

<li>"User opened mailbox" messages are now logged at the DEBUG
level instead of the INFO level.</li>

<li>auth_unix no longer requires users to be in the passwd

<li>AUTHENTICATE command now reports the protection mechanism in
use in the text of the tagged OK response</li>


<li>Use the header cache for SEARCH HEADER</li>

<li>Use "unspecified-domain" instead of server's hostname to fill
out RFC 822 addresses without the "@domain" part.</li>

<li>Make "reconstruct -r" with no args reconstruct every

<li>The configure script now defaults to using unix_pwcheck instead
of unix if the file /etc/shadow exists.</li>

<li>The location of the pwcheck socket directory now defaults to
"<tt>/var/ptclient/</tt>". It is controlled by the
"<tt>--with-statedir=DIR</tt>" option, which defaults to

<li>Bug fix: by using an certain address form, one could deliver to
a user's mailbox bypassing the ACL's.</li>

<li>Bug fix: un-fold header lines when parsing for the

<li>Delete quota roots when deleting the last mailbox that uses
them. Doesn't catch all cases, but should get over 99% of

<li>Implement plaintextloginpause configuration option, imposes
artificial delay on plaintext password logins.</li>

<li>Implement popminpoll configuration option, limits frequency of
POP3 logins.</li>

<li>Implement AFS PT server group support.</li>

<li>Remove persistence of POP3 LAST value and remove Status:

<li>Support the new ACL command set in the IMAP server.</li>

<li>Bug fix: Have to initialize reply to 0 in pop3d. Was causing
POP3 server to occasionally drop the connection during

<li>Bug fix: The COPY command wasn't issuing a [TRYCREATE] when
appropriate for sub-mailboxes of INBOX.</li>

<li>Bug fix: Renaming a mailbox wasn't correctly changing its

<li>Bug fix: Renaming a mailbox to itself, in order to move it to a
different partition, was not working correctly.</li>

<li>Update the AUTH support in pop3d to conform to the latest draft

<li>Update cyradm to use Tcl 7.5 instead of Tcl 7.4</li>

<li>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

<li>Implement newsspool configuration option, for separating the
directories for the news spool and the various cyrus.* IMAP server
index files.</li>

<li>Bug fix: permit empty flag list in APPEND command</li>

<li>Bug fix: deal with truncated Date: header values.</li>

<li>Bug fix: memory mapping code, deal better with 0-length maps,
since mmap() appears to crap out on that boundary condition.</li>

<li>Portability fix: if no strerror, have to define

<li>Bug fix: used append instead of lappend in cyradmin, preventing
use of any port other than IMAP.</li>

<li>When the client is streaming its commands, the IMAP server
attempts to stream its tagged responses.</li>

<li>Modify zephyr support to compile without Kerberos support.</li>

<li>Add a bunch of prototype declararations to the code.</li>

<li>In deliver, change the MULT support to instead use the LMTP

<li>imclient: support tagged intermediate replies and a default

<li>Implement some experimental protocol extensions for optimizing
disconnected use resynchronization. Most extensions are disabled by
default. Client authors should contact if
they wish to experiment with these.</li>

<li>Add map_stupidshared mapping module for older versions of
Digital Unix. It's not quite as bad as HPUX, but...</li>

<li>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.</li>

<li>The auth_xxx routines now create/take a state argument instead
of maintaining internal static state.</li>

<li>Solaris mktime() is buggy in some releases. Create and use
mkgmtime() for parsing date strings.</li>

<li>Message parsing routines now use memory mapping, though they
still copy data around in line-sized buffers.</li>

<h2>Changes to the Cyrus IMAP Server Since Version 1.3</h2>

<li>Implemented the "<tt>reconstruct -m</tt>" command, for
reconstructing the <tt>mailboxes</tt> file. <b>IMPORTANT:</b> it is
necessary to run the command "<tt>reconstruct -m</tt>" 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
<tt>mailboxes</tt> file in the configuration directory before
performing the conversion.</li>

<li>Mailbox names are now case sensitive, not case insensitive.
"<tt>INBOX</tt>" is the exception, and is treated as being

<li>Personal mailboxes now appear to their owners as being under
the "<tt>INBOX.</tt>" hierarchy. For example, the mailbox
"<tt></tt>" appears to the user "<tt>bovik</tt>" as
"<tt></tt>". The user may still refer to the mailbox with
the name "<tt></tt>".</li>

<li>Previously, the code used "<tt>anybody</tt>" as the name of the
group that all users are in, but the documentation used the name
"<tt>anyone</tt>". Changed the code to match the documentation. The
name "<tt>anybody</tt>" will be canonicalized to the name

<li>The install document now gives different recommended locations
for the server databases. The recommended location of the
configuration directory changed from "<tt>/usr/cyrus</tt>" to
"<tt>/var/imap</tt>" and the recommended location of the default
partition directory changed from "<tt>/usr/spool/cyrus</tt>" to
"<tt>/var/spool/imap</tt>". It is <b>NOT</b> 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 <tt>/etc/imapd.conf</tt> file.</li>

<li>Created a "<tt>make install</tt>" rule. See the <a
href="install.html">installation</a> document for all the new
corresponding <tt>configure</tt> options. Note the recommended
location of the "<tt>imapd</tt>", "<tt>pop3d</tt>", and
"<tt>deliver</tt>" programs has changed, this change needs to be
reflected in the "<tt>inetd.conf</tt>" and "<tt></tt>"

<li>New "<tt>login_unix_pwcheck</tt>" module and "<tt>pwcheck</tt>"
daemon, for improved shadow password support. See the
"<tt>pwcheck/README.pwcheck</tt>" file in the distribution for

<li>Renamed the "<tt>login_unix_shadow</tt>" module to

<li>Added a mail notification mechanism, using Zephyr.</li>

<li>Added a feature to automatically create user IMAP accounts.
Controlled by the "<tt>autocreatequota</tt>" config option.</li>

<li>Added the "<tt>logtimestamps</tt>" config option, for putting
timestamp information into protocol telemetry logs.</li>

<li>Beefed up the Kerberos checks in Configure to ensure the DES
library routines exist.</li>

<li>On some systems, the "<tt>echo</tt>" command with no arguments
emits a newline. Changed the installation document to instead use
the "<tt>true</tt>" command to create the "<tt>mailboxes</tt>"

<li>Store a redundant copy of a mailbox's ACL in the
<tt>cyrus.header</tt> file, so "<tt>reconstruct -m</tt>" may later
use it as a backup.</li>

<li>Had to remove the declaration of <tt>tcl_RcFileName</tt> for
the latest version of Tcl.</li>

<li>Make much more extensive use of memory mapping. Replace the
binary search module with one that searches a memory mapped

<li>Replaced the yacc-based RFC822 address parser with a hand-coded

<li>Replaced the et (error table) libary with a version that
doesn't require lex or yacc. Remove the lex/yacc checking from

<li>Safety feature: most programs now refuse to run as root.</li>

<li>Bug fix: Issue [TRYCREATE] tag on COPY command when

<li>Bug fix: The quoted-printable decoder wasn't ignoring trailing
whitespace, as required by MIME.</li>

<li>Bug fix: Don't spew cascade errors if the server gets an EOF
during/after reading an APPEND literal.</li>

<li>Bug fix: gmtmoff_gmtime.c was returning results with the wrong

<li>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.</li>

<li>Bug fix: rmnews wasn't removing some (un-indexed) article files

<li>Completely disabled the dropoff code for now. It will be
completely replaced when IMSP integration is implemented</li>

<li>Added workaround for the Linux mkdir() problem.</li>

<li>In Configure, use a more direct test for a working
shared-memory mmap</li>

<li>In collectnews, avoid O(n**2) behavior when processing articles
that have already expired.</li>

<li>Bug fix: append_addseen() would screw up if no messages were
previously seen.</li>

<li>Added the CMU-specific amssync and cmulocal directories.</li>

<li>Use memmove instead of bcopy.</li>

<li>Implemented the first pass of SMTP/MULT support in

<li>Added cacheid parameter to auth_setid(), for AFS PT server

<h2>Changes to the Cyrus IMAP Server Since Version 1.2</h2>
