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  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 is moderately security sensitive. It runs with  fixed
       low privilege and can run in a chrooted environment.  However, the pro-
       gram reads files from potentially 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  pub-
       lic 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  pro-
       gram.  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.
