(In reply to Rob Austein's message <SRA.12374181810.BABYL@XX.LCS.MIT.EDU>) I don't think it's fair to call a mailer "broken" because it retains the address of the original sender for reply purposes. If mailing-list redistributions eradicated the original From: line, replacing the original sender's address with that of the redistributor, their mailing lists would be far less useful. Ditto if our mailers replied according to the SMTP envelope rather than the body of the message. Note that the envelope's format is not specified by RFC 822, only the message header is -- and messages can be delivered by other means besides SMTP. Though RFC 822 doesn't define it, I've seen some mailing lists distribute messages with an Errors-To: line. This seems to be just what's needed to separate message replies from delivery error replies. Sendmail seems to support "Errors-To"; how many other mailers do? Stuart Levy, Minn. Supercomputer Center

I wonder if the complaint is more about mailers that DO NOT preserve the original From: line than those that do? I bring this up because I've noticed that my From: line has been changed when passing through various gateways, whenever I have been fortunate enough to establish return communications. This alteration of the From: line in the gateway has definately caused problems because the changes no longer reflect an accurate Return path. Now if my observations are correct, what mechnism can be used to ensure accurate return paths while permitting the various gateways to munge things before completing message transmission? I have been unable to establish the existence of any such mechanism and am forced to include a full return path in the body of the message to ensure return mail. I conclude, therfore, that mailers making this type of arbitrary change can be classed as broken. -- G.
