[comp.mail.misc] Vicious rewriting of From: lines

steve@thelake.UUCP (Steve Yelvington) (12/08/89)

Based on John Chew's "Inter-Network Mail Guide," I recently tried to send
a note to someone whose only e-mail address is on Compuserve. 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 <uccba!73607.1231@hal.cwru.edu>... 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.

Fingerprints were left by:

cwjcc.INS.CWRU.Edu
saqqara.cis.ohio-state.edu
tut.cis.ohio-state.edu
mailrus.cc.umich.edu
wuarchive.wustl.edu
swbatl.sbc.com
pwcs.StPaul.GOV
stag.UUCP

I regularly have mail pass through wuarchive, swbatl, pwcs and stag
without anything horrid happening.

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?

Do I need to include X-Really-From-Before-Header-Mangling: ?
