It's a closed mailing list. I assume by Return-Path they really mean the From: header. Take a look at gnus-posting-styles (in the Gnus info) -- it may do what you want. For instance, at work, I set gnus-posting-styles to the following so that when I read my IMAP mail on my ISP account from work I reply to it as if I were answering from my ISP. (setq gnus-posting-styles '(("^nnimap\\+best" (address "mattdav+matt@best.com")))) -- matta. ^ permalink raw reply [flat|nested] 6+ messages in thread

If the Return-Path is unreachable due to a firewall, lots of mail servers will reject the mail, whether the recipient is a mailing list or not. Postmasters don't like accepting mail that they won't be able to bounce later if the delivery fails. -- Frank Cringle, fdc@cliwe.ping.de voice: (+49 2304) 467101; fax: 943357 ^ permalink raw reply [flat|nested] 6+ messages in thread

That's pretty strict. > What I was wondering was whether the Return-Path: should be my > e-mail address or the account I am posting from (which is > unreachable due to a firewall). The Return-Path: is not set by Gnus, but by sendmail (or whatever MTA is in use). If it isn't a valid e-mail address, then it is a problem with the MTA. But this also means you can't really get around your problem. -- matta ^ permalink raw reply [flat|nested] 6+ messages in thread

Matt Armstrong <matta@geoworks.com> writes: > The Return-Path: is not set by Gnus, but by sendmail This is similar to the difficulty some of us have with Gnus' generation of Sender. This one is partly Gnus' "fault", if you can call it that. sendmail is invoked with `"-f" (user-login-name)' in message.el, to set the origin user positively; a typical sendmail installation will then adjust that to be your-name@your.host.where.you.sent.the.mail. For many (most?) of us, that's not really quite desirable, since (e.g.) my Return-Path (which is the envelope origin from SMTP Mail From:<>, converted to a header upon delivery) shows karl@pocari-sweat.jprc.com but my normal address is karl@jprc.com. The only way to hack around this is to modify the function message-send-mail-with-sendmail from message.el, to substitute the "-f" argument with a string that's more appropriate for you. With regard to the standards for Return-Path, RFC822 observes that it should be a _route_ back to the originator, i.e., it should show relay hops; RFC1123 in turn says that failure notifications should be sent back to the originator with the route information deleted, that is, "If the address is an explicit source route, it SHOULD be stripped down to its final hop." ??? Then what's the point of providing the source route in the first place? It seems to me that Return-Path's value has become very limited in an environment where source-routed mail is vastly deprecated, and just plain not supported by many. I know that, when I did serious sendmail work years ago, I shot all source routes on sight. You could very well substitute the use of (user-login-name) for the "-f" argument in message-send-mail-with-sendmail with the variable user-mail-address; the result should give the effect you need, and not create any interoperability problems -- mail will still show a proper way to return to you. That said, this mailing list's requirement of matching Return-Path is indeed pretty peculiar. --karl ^ permalink raw reply [flat|nested] 6+ messages in thread
