I'd like to be able to publish DNS records announcing my domain's *outbound* mail servers, with nice abbreviated forms to say "they're the same as my inbound (MX) records" or "any IP in x.y.z/24". Then cooperative ISPs (like say America Online) could refuse any email from my domain that originated from some random cable modem, instead of accepting it and then flooding me with 20000 bounce messages.What about this email from you which came to me from Merit and not your mail server? Would break mailing lists and listserves unless the from field is overwritten.
No, because a mailer doesn't look at headers - it looks at the SMTP envelope, and mailinglists set this to point to an address of themselves to monitor bounces. Greetz, Peter -- MegaBIT - open air networking event - http://www.megabit.nl/
