It's easy enough to send all mail into a pipe(8) command.
/etc/postfix/main.cf:
transport_maps = static:javapipe
/etc/postfix/master.cf:
javapipe .... pipe
user=xx flags=yy argv=/some/where/java-program $sender $recipient
However:
- How would Postfix know what domains to receive? It's a bad idea
to accept mail from any client to any destination. That would be
an open relay.
- How would Postfix know what recipients are valid? It's a bad idea
to accept-then-bounce mail for non-existent recipients.
