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 with-
       out  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 pub-
       lic 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  mes-
       sage  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 includ-
       ing examples.

CONTENT INSPECTION CONTROLS
       content_filter (empty)
	      After  the  message  is  queued,	send  the  entire message to the specified trans-
	      port:destination.

       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
	      delivery, long lines are reconstructed.

       max_idle (100s)
	      The  maximum amount of time that an idle Postfix daemon process waits for an incom-
	      ing connection before terminating voluntarily.

       max_use (100)
	      The maximal number of incoming connections that a Postfix daemon process will  ser-
	      vice 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".
