Benny, i want to limit mail sent via php mainly, so i can't limit via sasl simply because users aren't authenticated.
Of course i can't limit the host ip (all mail sent from my webserver). The most beautiful thing would be limiting system user (each user has an entry in /etc/passwd). Limiting the sender would be unuseful, because all spammers randomiza the sender, bypassing the limit. Now, i know that cPanel with Exim has a limit of this tipe. I'll request them WHAT is exactly limited (maybe we can replicate with postfix). I'll also write to the postfix-policyd mailing list. Sahil, maybe we can continue here? Postfixfw rules are completely in topic and maybe we can help someone else...
