"uucp" is not a valid top-level domain. Similarly, > From: tct!chip >is insufficient due to no "@right.hand.side." Okay. I concede that Karl is right for the example he gives. Let me put forth two more examples, and see what would happen. 1. Let us suppose that the hypothetical machine "tct" with UUCP connection to "osu-cis" has just been registered under the domain TCT.COM. (I hope to do so shortly.) In that case, my hypothetical message will arrive at osu-cis with the envelope: From tct!chip but the header will be valid RFC822: From: chip@tct.com Will this header be rewritten into a bang path just because the mail came in from UUCP? I expect that it won't, since it's already RFC822. 2. (This is the example that sparked my original suggestion.) If mail from BAR.COM is being delivered to TCT.COM via UUCP from osu-cis, will the headers: From: foo@bar.com To: chip@tct.com be rewritten into bang paths just because my site's transport of choice is UUCP? This munging is *not* necessary. It is, in my opinion, rude to mung headers of UUCP sites which are cooperative enough to register with the DNS and comply with RFC822. -- Chip Salzenberg at Teltronics/TCT , "Please don't send me any more of yer scandalous email, Mr. Salzenberg..." -- Bruce Becker
