PICKUP(8)                                               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 world-writable  maildrop  directory,  and
       feeds  it into the cleanup(8) daemon.  Ill-formatted files
       are deleted without notifying the originator.   This  pro-
       gram 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 submit-
       ting  user and 2) can access the Postfix private IPC chan-
       nels.  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  send-
       ing  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.
