PICKUP(8)                                                                                          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  origina-tor. originator.
       tor.  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).

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 exam-ples. examples.
       ples.

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 filtering, or address mapping.

MISCELLANEOUS CONTROLS
       config_directory (see 'postconf -d' output)
              The default location of the Postfix main.cf and master.cf configuration files.

       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 waits for an incoming connec-tion connection
              tion before terminating voluntarily.

       max_use (100)
              The maximal number of incoming connections that a Postfix daemon process will  service  before
              terminating voluntarily.

       process_id (read-only)
              The process ID of a Postfix command or daemon process.

       process_name (read-only)
              The process name of a Postfix command or daemon process.

       queue_directory (see 'postconf -d' output)
              The location of the Postfix top-level queue directory.

       syslog_facility (mail)
              The syslog facility of Postfix logging.

       syslog_name (see 'postconf -d' output)
              The  mail system name that is prepended to the process name in syslog records, so that "smtpd"
              becomes, for example, "postfix/smtpd".
