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.
====================================================================
maildrop. See the Postfix MAILDROP_README file for details.
Also specify in main.cf: maildrop_destination_recipient_limit=1

====================================================================
Recent Cyrus versions can use the existing “lmtp” master.cf entry.
Specify in cyrus.conf:
lmtp cmd=“lmtpd -a” listen=“localhost:lmtp” proto=tcp4
Specify in main.cf one or more of the following:
mailbox_transport = lmtp:inet:localhost
virtual_transport = lmtp:inet:localhost
