BOING! When it left my system, it was addressed like so: To: 73607.1231@compuserve.com From: steve@thelake.UUCP (Steve Yelvington) Reply-To: pwcs.StPaul.GOV!stag!thelake!steve So what happened to this mail? It bounced at hal.cwru.edu with this error message: ----- Transcript of session follows ----- >>> RCPT To:<73607.1231@uccba.uc.edu> <<< 550 <73607.1231@uccba.uc.edu>... User unknown: Not a typewriter 550 ... User unknown I was fairly certain that the person to whom I had addressed the mail was not a typewriter, and gratified to have my grip on reality verified by hal, but I am quite confused about uccba.uc.edu and what it has to do with Ohio-based Compuserve. Hal very politely returned my mail intact. Then I looked at the header: To: 73607.1231@compuserve.com From: steve@cis.ohio-state.edu (Steve Yelvington) Reply-To: wuarchive!swbatl!pwcs!stag!thelake!steve@mailrus.cc.umich.edu This is the first time I've been teleported to Ohio State. Once I was teleported to Apple Computer, which was almost as surprising.

I don't mind the rewriting of Reply-To:, since it was done correctly, but who would ever have a good reason to rewrite the From: line?
