Yes, it's the 'address_verify_sender' parameter, see; http://www.postfix.org/postconf.5.html#address_verify_sender http://www.postfix.org/postconf.5.html#double_bounce_sender Ours is set to 'senderverificat...@dtnx.net', since we use it for SAV as well, and that's where it's visible to others. We've seen similar setups from others as well, as well as the null sender address, 'postmaster' and so on. For use with your own backend (as RAV) it probably won't matter as much, but could still be useful for instant recognition while reading logs. HTH, Jona
