You could some perl in an alias behind local postmaster that forwarded a copy of the postfix session transcript to the "mail from:" address, since the session transcript will typically only show up in the SMTP client logs, not all the back to the "mail from:". btw, if you do this bit of perl, I'd appreciate a copy. We love postfix here. Even built an entire anti-spam front end out of it: http://IMGate.MEIway.com for the Ipswitch Imail crowd, but the concept applies to any mail server.
