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 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 daemon does not interact with the outside
       world.
SECURITY
       The pickup daemon is  moderately  security  sensitive.  It
       runs  with  fixed  low privilege and can run in a chrooted
       environment.  However, the program reads files from poten-
       tially  hostile  users.   The pickup 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 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.
       queue_directory
              Top-level directory of the Postfix queue.
