postfwd - limit outgoing mail

[Andrea Ganduglia]

Hello!

How can I limit outgoing mail with postfwd?

I tried a simple rule like id=DEFAULT; action=dunno

Dec 16 18:44:40 sheldon postfwd[4000]: [RULES] rule=0, id=DEFAULT,
client=*****[000.000.000.000], sender=<info@****>,
recipient=<info@****>, helo=<****>, proto=ESMTP, state=RCPT, delay=0s,
hits=DEFAULT, action=dunno

but I don't figure out how can I add a rule for a outgoing traffic.

Thanks!
