   8
   9 <b>NAME</b>
  10        pickup - Postfix local mail pickup
  11
  12 <b>SYNOPSIS</b>
  13        <b>pickup</b> [generic Postfix daemon options]
  14
  15 <b>DESCRIPTION</b>
  16        The  <a href="pickup.8.html"><b>pickup</b>(8)</a>  daemon  waits  for hints that new mail has
  17        been dropped into the <b>maildrop</b>  directory,  and  feeds  it
  18        into  the  <a href="cleanup.8.html"><b>cleanup</b>(8)</a>  daemon.   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.
