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

queue_directory (see ’postconf -d’ output)
The location of the Postfix top-level queue directory.
The syslog facility of Postfix logging.
syslog_name (see ’postconf -d’ output)
