This 19 program expects to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager. 20 21<b>STANDARDS</b> 22 None. The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon does not interact with the outside world. 23 24<b>SECURITY</b> 25 The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is moderately security sensitive. It runs with 26 fixed low privilege and can run in a chrooted environment. However, 27 the program reads files from potentially hostile users. The <a href="pickup.8.html"><b>pickup</b>(8)</a> 28 daemon opens no files for writing, is careful about what files it opens 29 for reading, and does not actually touch any data that is sent to its 30 public service endpoint. 31 32<b>DIAGNOSTICS</b> 33 Problems and transactions are logged to <b>syslogd</b>(8). 34 35<b>BUGS</b> 36 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. 37 It could avoid message copying overhead by sending a file descriptor 38 instead of file data, but then the already complex <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon 39 would have to deal with unfiltered user data. 40 41<b>CONFIGURATION PARAMETERS</b> 42 As the <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is a relatively long-running process, up to an 43 hour may pass before a <a href="postconf.5.html"><b>main.cf</b></a> change takes effect. Use the command 44 "<b>postfix reload</b>" command to speed up a change. 45 46 The text below provides only a parameter summary. See <a href="postconf.5.html"><b>postconf</b>(5)</a> for 47 more details including examples. 48 49<b>CONTENT INSPECTION CONTROLS</b> 50 <b><a href="postconf.5.html#content_filter">content_filter</a> (empty)</b> 51 After the message is queued, send the entire message to the 52 specified <i>transport:destination</i>. 53 54 <b><a href="postconf.5.html#receive_override_options">receive_override_options</a> (empty)</b> 55 Enable or disable recipient validation, built-in content filter- 56 ing, or address mapping. 57 58<b>MISCELLANEOUS CONTROLS</b> 59 <b><a href="postconf.5.html#config_directory">config_directory</a> (see 'postconf -d' output)</b> 60 The default location of the Postfix <a href="postconf.5.html">main.cf</a> and <a href="master.5.html">master.cf</a> con- 61 figuration files. 62 63 <b><a href="postconf.5.html#ipc_timeout">ipc_timeout</a> (3600s)</b> 64 The time limit for sending or receiving information over an 65 internal communication channel. 66 67 <b><a href="postconf.5.html#line_length_limit">line_length_limit</a> (2048)</b> 68 Upon input, long lines are chopped up into pieces of at most 69 this length; upon delivery, long lines are reconstructed. 70 71 <b><a href="postconf.5.html#max_idle">max_idle</a> (100s)</b> 72 The maximum amount of time that an idle Postfix daemon process 73 waits for an incoming connection before terminating voluntarily. 74 75 <b><a href="postconf.5.html#max_use">max_use</a> (100)</b> 76 The maximal number of incoming connections that a Postfix daemon 77 process will service before terminating voluntarily. 78 79 <b><a href="postconf.5.html#process_id">process_id</a> (read-only)</b> 80 The process ID of a Postfix command or daemon process. 81 82 <b><a href="postconf.5.html#process_name">process_name</a> (read-only)</b> 83 The process name of a Postfix command or daemon process. 84 85 <b><a href="postconf.5.html#queue_directory">queue_directory</a> (see 'postconf -d' output)</b> 86 The location of the Postfix top-level queue directory. 87 88 <b><a href="postconf.5.html#syslog_facility">syslog_facility</a> (mail)</b> 89 The syslog facility of Postfix logging. 90 91 <b><a href="postconf.5.html#syslog_name">syslog_name</a> (see 'postconf -d' output)</b> 92 The mail system name that is prepended to the process name in 93 syslog records, so that "smtpd" becomes, for example, "post- 94 fix/smtpd". 95 96<b>SEE ALSO</b> 97 <a href="cleanup.8.html">cleanup(8)</a>, message canonicalization 98 <a href="sendmail.1.html">sendmail(1)</a>, Sendmail-compatible interface 99 <a href="postdrop.1.html">postdrop(1)</a>, mail posting agent 100 <a href="postconf.5.html">postconf(5)</a>, configuration parameters 101 <a href="master.5.html">master(5)</a>, generic daemon options 102 <a href="master.8.html">master(8)</a>, process manager 103 syslogd(8), system logging 104 105<b>LICENSE</b> 106 The Secure Mailer license must be distributed with this software. 107 108<b>AUTHOR(S)</b> 109 Wietse Venema 110 IBM T.J.
