I found the above link when looking for a how to for configuring postfix to bounce email BEFORE the initial MTA transaction is complete. I can't seem to find one for postfix. I want a sending MTAs to get a 550 error if spamc/spamd determine a mail is spammy so non spam senders get some sort of feedback that their message has been tossed and not delivered. For obvious reasons you can't do this as a bounce to the From: or Reply-To: header emails so it has to happen during the initial MTA transaction. Can someone point me to a how to for this?
Thanks, Tom
