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.
