<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 world-writable <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 pro-
|
|
gram 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 runs with superuser privileges so that
|
|
it 1) can open a queue file with the rights of the submit-
|
|
ting user and 2) can access the Postfix private IPC chan-
|
|
nels. On the positive side, the program can run chrooted,
|
|
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.

|
|
transport table.
