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.
