It makes sure that the envelope sender address cannot be from one of your domains unless the mail is comming from a trusted address. It is turned on by the same flag that disallows blind relaying (-f on the commad line or 'norelay on' in the config file). It still needs a bit of work, i.e., I should also check the From: address in the message itself. I just wanted to take it one step at a time. Complaints to me.
