Message-ID: <208@frcs.UUCP> Date: 3 Dec 90 14:14:06 GMT Followup-To: comp.mail.misc Organization: Flagship Wide Area Networks (Pty) Ltd Lines: 29 We have a dispute between the administrators of a few local machines. One of the machines runs `sendmail' (for bizzare reasons), and has a `sendmail.cf' file that re-writes the `To:' and `From:' fields in all forwarded mail. The effect on the headers is roughly as follows (`gatebox' is the [ficticious] `sendmail' pervert): incoming outgoing To: user@toaster To: toaster!user@gatebox From: me@tinytoy From: tinytoy!me@gatebox The administrator of this particular machine feels that this is perfectly reasonable, and even desirable, so that mail gets routed the way that they think fit. However, others of us think that this is not terribly sociable, and want our addresses left alone. I have tried digging through RFC822, but it has cast no light on the subject. My gut feel, though, is that each mailer should only rewrite the `Path:' field (and add a fifteen-line `Received:' field). The rest should surely be left alone (after all, _I_ know who I am). Are there any Mail Gurus out there who can elighten us? ---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=--- Paul Nash Flagship Wide Area Networks (Pty) Ltd paul@frcs.UUCP ...!uunet!ddsw1!proxima!frcs!paul Brought to you by Super Global Mega Corp .com
