Lately, I've been seeing an extrordinary number of confirmation replies addressed to owner-listserv. After eliminating the ones from MSMAIL sites ( which used to include almost all of them ) I still had a pile. After running tests with postmasters at several of the sites - admittedly a small sample - I think I see the beginning of a pattern. Mail that passes thru <some> UUnet gateways goes in with both a Return-path and a From Header, but comes out with 2 From headers - ie the return-path header is changed to a FROM header so that when the eventual recipient does a reply, his mailer ( compliant ) uses the first FROM as the source of the reply address. has anyone else seen this ? < lightbulb going on > is this why LMAIL always uses the LAST of any duplicate headers ? -mike
