Oh dear, that's all really too much trouble. I have OpenBSD's spamd running in front of my MTA. A script checks all greylisted entries for invalid recipients with <> sender and tarpits them. You cannot have a legitimate bounce going to an invalid sender for bleedin' obvious reasons. So stick it to 'em. It wastes resources on all the misconfigured bounce-instead-of-reject dummies out there and places no load on my lovely Postfix server. Heh! *** NOTE *** Please DO NOT CC me. I <am> subscribed to the list. Mail to the sender address that does not originate at the list server is tarpitted. The reply-to: address is provided for those who feel compelled to reply off list.
