Ill-formatted files are 19 deleted without notifying the originator. This program 20 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 out- 24 side world. 25 26<b>SECURITY</b> 27 The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is moderately security sensitive. It 28 runs with fixed low privilege and can run in a chrooted 29 environment. However, the program reads files from poten- 30 tially hostile users. The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon opens no files 31 for writing, is careful about what files it opens for 32 reading, and does not actually touch any data that is sent 33 to its public service endpoint. 34 35<b>DIAGNOSTICS</b> 36 Problems and transactions are logged to <b>syslogd</b>(8). 37 38<b>BUGS</b> 39 The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon copies mail from file to the 40 <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon. It could avoid message copying over- 41 head by sending a file descriptor instead of file data, 42 but then the already complex <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon would have 43 to deal with unfiltered user data. 44 45<b>CONFIGURATION PARAMETERS</b> 46 As the <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon is a relatively long-running 47 process, up to an hour may pass before a <a href="postconf.5.html"><b>main.cf</b></a> change 48 takes effect. Use the command "<b>postfix reload</b>" command to 49 speed up a change. 50 51 The text below provides only a parameter summary.
