A project for another time. I now think I was wrong saying that postfix wasn't the right tool for this. Postfix can do an amazing number of things. I had forgotten that it can rewrite addresses in headers for both outgoing and incoming email. Sorry for replying before my brain was fully engaged. :-) See http://www.postfix.org/ADDRESS_REWRITING_README.html In particular, look at the "Address rewriting when mail is received" and "Address rewriting when mail is delivered" sections. I'm not sure, but canonical address mapping sounds like what you want: http://www.postfix.org/ADDRESS_REWRITING_README.html#canonical This isn't the same as just delivering an email to an alias address. It actually rewrites envelope and message header addresses. If this does what you want, it should work no matter what mail client you use. So you can rewrite all your addresses to a single canonical one. I don't know if postfix will remove duplicates (in case multiple non-canonical addresses appear as recipients), but it probably wouldn't matter for the purpose of replying. So here's a guess: /etc/postfix/master.cf: canonical_maps = hash:/etc/postfix/canonical /etc/postfix/canonical EmailB EmailA EmailC EmailA EmailD EmailA EmailE EmailA You'd need to run "postmap hash:/etc/postfix/canonical" to prepare the canonical.db for use whenever you change the canonical file. Good luck. cheers, raf
