Ill-formatted files are deleted without notifying the originator. This program expects to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager. <b>STANDARDS</b> None. The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon does not interact with the outside world. <b>SECURITY</b> The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is moderately security sensitive. It runs with fixed low privilege and can run in a chrooted environment. However, the program reads files from potentially hostile users. The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon opens no files for writing, is careful about what files it opens for reading, and does not actually touch any data that is sent to its public service endpoint. <b>DIAGNOSTICS</b> Problems and transactions are logged to <b>syslogd</b>(8). <b>BUGS</b> The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon copies mail from file to the <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon. It could avoid message copying overhead by sending a file descriptor instead of file data, but then the already complex <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon would have to deal with unfiltered user data. <b>CONFIGURATION PARAMETERS</b> As the <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is a relatively long-running process, up to an hour may pass before a <a href="postconf.5.html"><b>main.cf</b></a> change takes effect. Use the command "<b>postfix reload</b>" command to speed up a change. The text below provides only a parameter summary. See <a href="postconf.5.html"><b>postconf</b>(5)</a> for more details including examples. <b>CONTENT INSPECTION CONTROLS</b> <b><a href="postconf.5.html#content_filter">content_filter</a> (empty)</b> After the message is queued, send the entire message to the specified <i>transport:destination</i>. <b><a href="postconf.5.html#receive_override_options">receive_override_options</a> (empty)</b> Enable or disable recipient validation, built-in content filter- ing, or address mapping. <b>MISCELLANEOUS CONTROLS</b> <b><a href="postconf.5.html#config_directory">config_directory</a> (see 'postconf -d' output)</b> The default location of the Postfix <a href="postconf.5.html">main.cf</a> and <a href="master.5.html">master.cf</a> con- figuration files. <b><a href="postconf.5.html#ipc_timeout">ipc_timeout</a> (3600s)</b> The time limit for sending or receiving information over an internal communication channel. <b><a href="postconf.5.html#line_length_limit">line_length_limit</a> (2048)</b> Upon input, long lines are chopped up into pieces of at most this length; upon delivery, long lines are reconstructed. <b><a href="postconf.5.html#max_idle">max_idle</a> (100s)</b> The maximum amount of time that an idle Postfix daemon process waits for an incoming connection before terminating voluntarily. <b><a href="postconf.5.html#max_use">max_use</a> (100)</b> The maximal number of incoming connections that a Postfix daemon process will service before terminating voluntarily. <b><a href="postconf.5.html#process_id">process_id</a> (read-only)</b> The process ID of a Postfix command or daemon process. <b><a href="postconf.5.html#process_name">process_name</a> (read-only)</b> The process name of a Postfix command or daemon process. <b><a href="postconf.5.html#queue_directory">queue_directory</a> (see 'postconf -d' output)</b> The location of the Postfix top-level queue directory. <b><a href="postconf.5.html#syslog_facility">syslog_facility</a> (mail)</b> The syslog facility of Postfix logging. <b><a href="postconf.5.html#syslog_name">syslog_name</a> (see 'postconf -d' output)</b> A prefix that is prepended to the process name in syslog records, so that, for example, "smtpd" becomes "prefix/smtpd". <b>SEE ALSO</b> <a href="cleanup.8.html">cleanup(8)</a>, message canonicalization <a href="sendmail.1.html">sendmail(1)</a>, Sendmail-compatible interface <a href="postdrop.1.html">postdrop(1)</a>, mail posting agent <a href="postconf.5.html">postconf(5)</a>, configuration parameters <a href="master.5.html">master(5)</a>, generic daemon options <a href="master.8.html">master(8)</a>, process manager syslogd(8), system logging <b>LICENSE</b> The Secure Mailer license must be distributed with this software. <b>AUTHOR(S)</b> Wietse Venema IBM T.J.
