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

#maildrop unix - n n - - pipe
