Dear all, I have some experiences on postfix.
Currently i work on isp and we have one outgoing server using postfix+amavis+clamav+spamassassin on freebsd, running well. We have plan to migrate our MXs from qpsmtpd+qmail to postfix+amavis and my problem is i can't find way to implement badmailfromto filtering on postfix. Please point me how to setup this type filtering on postfix. About badmailfromto (from qpsmtpd plugins website): Much like the similar check_badmailfrom, this plugin references both the FROM: and TO: lines, and if they both are present in the badmailfromto config file (a tab delimited list of FROM/TO pairs), then the message is blocked as if the recipient (TO) didn't exist. This is specifically designed to not give the impression that the sender is blocked (good for cases of harassment). Based heavily on check_badmailfrom. Thank you.
