<b><a name="description">DESCRIPTION</a></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><a name="standards">STANDARDS</a></b>
None. The <a href="pickup.8.html"><b>pickup</b>(8)</a> daemon does not interact with the outside world.
<b><a name="security">SECURITY</a></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><a name="diagnostics">DIAGNOSTICS</a></b>
Problems and transactions are logged to <b>syslogd</b>(8) or <a href="postlogd.8.html"><b>postlogd</b>(8)</a>.
<b><a name="bugs">BUGS</a></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><a name="configuration_parameters">CONFIGURATION PARAMETERS</a></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.
