PICKUP(8)							     PICKUP(8)

       pickup - Postfix local mail pickup

       pickup [generic Postfix daemon options]

       The  pickup(8)  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.

       None. The pickup(8) daemon does not interact with the outside world.

       The pickup(8) daemon is moderately security  sensitive.	It  runs  with
       fixed  low  privilege  and can run in a chrooted environment.  However,
       the program reads files from potentially hostile users.	The  pickup(8)
       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.

       Problems and transactions are logged to syslogd(8).

       The  pickup(8)  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.

       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.

       more details including examples.
