"Relaying" implies passing mail to another server via network. Also, I have no idea why you would not want Postfix to do its job, but anyway: Postfix can pass incoming mail to a binary during local delivery. You can for example set up an alias (http://www.postfix.org/aliases.5.html): # /etc/aliases mybinary: |/path/to/binary Make sure to configure 'alias_database' accordingly. Sending mail to mybin...@host.domain.tld should then be enough to invoke the binary (with default values for 'mydestination'). -Ralph
