This 20 program expects to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager. 21 22<b>STANDARDS</b> 23 None. The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon does not interact with the outside world. 24 25<b>SECURITY</b> 26 The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is moderately security sensitive. It runs with 27 fixed low privilege and can run in a chrooted environment. However, 28 the program reads files from potentially hostile users. The <a href="pickup.8.html"><b>pickup</b>(8)</a> 29 daemon opens no files for writing, is careful about what files it opens 30 for reading, and does not actually touch any data that is sent to its 31 public service endpoint. 32 33<b>DIAGNOSTICS</b> 34 Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>. 35 36<b>BUGS</b> 37 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. 38 It could avoid message copying overhead by sending a file descriptor 39 instead of file data, but then the already complex <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon 40 would have to deal with unfiltered user data. 41 42<b>CONFIGURATION PARAMETERS</b> 43 As the <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is a relatively long-running process, up to an 44 hour may pass before a <a href="postconf.5.html"><b>main.cf</b></a> change takes effect. Use the command 45 "<b>postfix reload</b>" command to speed up a change. 46 47 The text below provides only a parameter summary.
