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 <b>pickup</b> 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 with-
out 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 <b>pickup</b> daemon does not interact with the outside
world.
<b>SECURITY</b>
The <b>pickup</b> 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 <b>pickup</b> 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 <b>pickup</b> 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 send-
ing 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</b> <b>PARAMETERS</b>
The following <b>main.cf</b> parameters are especially relevant
to this program. See the Postfix <b>main.cf</b> file for syntax
details and for default values. Use the <b>postfix</b> <b>reload</b>
command after a configuration change.
<b>Content</b> <b>inspection</b> <b>controls</b>
<b>content</b><i>_</i><b>filter</b>
The name of a mail delivery transport that filters
mail and that either bounces mail or re-injects the
result back into Postfix. This parameter uses the
same syntax as the right-hand side of a Postfix
transport table.
<b>Miscellaneous</b>
<b>always</b><i>_</i><b>bcc</b>
Address to send a copy of each message that enters
the system.
<b>queue</b><i>_</i><b>directory</b>
Top-level directory of the Postfix queue.
