PICKUP(8postfix)                                                                    PICKUP(8postfix)



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 direc‐
       tory, and feeds it into the cleanup(8) daemon.  Ill-formatted files are deleted without noti‐
       fying 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  end‐
       point.

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 com‐
       plex 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:desti‐
              nation.

       receive_override_options (empty)
              Enable or disable recipient validation, built-in content filtering,  or  address  map‐
              ping.

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  deliv‐
              ery, long lines are reconstructed.

       max_idle (100s)
              The  maximum  amount of time that an idle Postfix daemon process waits for an incoming
              connection 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)
              A  prefix  that is prepended to the process name in syslog records, so that, for exam‐
              ple, "smtpd" becomes "prefix/smtpd".

       Available in Postfix 3.3 and later:

       service_name (read-only)
              The master.cf service name of a Postfix daemon process.

       Available in Postfix 3.5 and later:

       info_log_address_format (external)
              The email address form that will be used in non-debug logging (info, warning, etc.).
