PICKUP(8) PICKUP(8)
|
|
|
|
<b>NAME</b>
|
|
pickup - Postfix local mail pickup
|
|
|
|
<b>SYNOPSIS</b>
|
|
<b>pickup</b> [generic Postfix daemon options]
|
|
|
|
<b>DESCRIPTION</b>
|
|
The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon waits for hints that new mail has
|
|
been dropped into the <b>maildrop</b> directory, and feeds it
|
|
into the <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon. 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 out-
|
|
side 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 poten-
|
|
tially 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 over-
|
|
head 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.
