      Interfaces to non-Postfix software. Be sure to examine the manual
      pages of the non-Postfix software to find out what options it wants.

      Many of the following services use the Postfix pipe(8) delivery
      agent.  See the pipe(8) man page for information about ${recipient}
      and other message envelope options.

      Recent Cyrus versions can use the existing "lmtp" master.cf entry.

      Specify in cyrus.conf:

      Specify in main.cf one or more of the following:
