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

NAME

       pickup - Postfix local mail pickup

SYNOPSIS

       pickup [generic Postfix daemon options]

DESCRIPTION

       The  pickup  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 daemon does not interact with the outside world.

SECURITY

       The pickup daemon runs with superuser privileges so that it 1) can open a queue file with the rights of the  submitting	user  and  2)  can
       access  the Postfix private IPC channels.  On the positive side, the program can run chrooted, 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 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

       The  following  main.cf parameters are especially relevant to this program. See the Postfix main.cf file for syntax details and for default
       values. Use the postfix reload command after a configuration change.

Content inspection controls
       content_filter
	      The name of a mail delivery transport that filters mail and that either bounces mail or re-injects the  result  back  into  Postfix.
	      This parameter uses the same syntax as the right-hand side of a Postfix transport table.

Miscellaneous
       always_bcc
	      Address to send a copy of each message that enters the system.

       mail_owner
	      The process privileges used while not opening a maildrop file.
