PICKUP(8)                   System Manager's Manual                  PICKUP(8)

NAME
       pickup - Postfix local mail pickup
SYNOPSIS
       pickup [generic Postfix daemon options]
DESCRIPTION
       The  pickup(8)  daemon  waits  for hints that new mail has been dropped
       into the maildrop directory, and feeds it into the  cleanup(8)  daemon.
       Ill-formatted files are deleted without notifying the originator.  This
       program expects to be run from the master(8) process manager.
STANDARDS
       None. The pickup(8) daemon does not interact with the outside world.
SECURITY
       The pickup(8) 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  pickup(8)
       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.
DIAGNOSTICS
       Problems and transactions are logged to syslogd(8) or postlogd(8).
BUGS
       The  pickup(8)  daemon  copies mail from file to the cleanup(8) daemon.
       It could avoid message copying overhead by sending  a  file  descriptor
       instead  of  file  data, but then the already complex cleanup(8) daemon
       would have to deal with unfiltered user data.
CONFIGURATION PARAMETERS
       As the pickup(8) daemon is a relatively long-running process, up to  an
       hour  may  pass  before a main.cf change takes effect.  Use the command
       "postfix reload" command to speed up a change.
       The text below provides only a parameter summary. See  postconf(5)  for
       more details including examples.
CONTENT INSPECTION CONTROLS
       content_filter (empty)
              After  the  message  is  queued,  send the entire message to the
              specified transport:destination.
       receive_override_options (empty)
              Enable or disable recipient validation, built-in content filter-
              ing, or address mapping.
MISCELLANEOUS CONTROLS
       config_directory (see 'postconf -d' output)
              The  default  location of the Postfix main.cf and master.cf con-

       ipc_timeout (3600s)
              The time limit for sending  or  receiving  information  over  an
              internal communication channel.
       line_length_limit (2048)
              Upon  input,  long  lines  are chopped up into pieces of at most
              this length; upon delivery, long lines are reconstructed.
       max_idle (100s)
              The maximum amount of time that an idle Postfix  daemon  process
