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).

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 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 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)
	      The mail system name that is prepended to the process name in syslog records, so that "smtpd" becomes, for example, "postfix/smtpd".
