    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 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.

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

           queue_directory
                  Top-level directory of the Postfix queue.
