man 1 postfix

       The following commands are implemented:

       check  Warn about bad directory/file ownership or permissions, and cre-
              ate missing directories.

       start  Start the Postfix mail system. This also runs the  configuration
              check described above.

This does not re-create any files needed for chroot operation,
as the process is operating system (and version) dependent.

It contains

- in-transit mail

- postfix-owned directories

- chroot support

As email presents is a write-intensive load, a good quality disk
drive is recommended.
