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

       As the pickup(8) daemon is a relatively long-running process, up to  an
       hour  may  pass  before a main.cf change takes effect.  Use the command
       "postfix reload" command to speed up a change.

       The text below provides only a parameter summary. See  postconf(5)  for
       more details including examples.

       daemon_timeout (18000s)

       max_use (100)

              mon process terminates.

       process_id (read-only)
              The process ID of a Postfix command or daemon process.
