This isn't a Mailman configuration problem as far as I can see -- just make a vanilla configuration based on the desired posting address. The problems are in routing to Mailman via fetchmail and Postfix. Since the tranport_maps take precedence over pretty much everything, and can be address-specific, just put the @gmail.com addresses he uses in there in the usual way. Then tell fetchmail to forward those addresses as is to Postfix's SMTP (depending on what other mail it needs to handle he might want to set up a configuration for an smtpd on port 8025, but probably not necessary). Maybe it's convenient for fetchmail to set Postfix's extension separator to '-' so that "cufsalumni-*@gmail.com" addresses are recognized as "[email protected]" variants by Postfix. The transport_maps will pick those addresses (and only those cufsalumni*@gmail.com addresses of any gmail.com addresses) and forward them to Mailman, which will DTRT. The problems I see with routing have to do with the impossibility of spoofing a Gmail origin for verifications and notifications, and anonymous lists etc that configure From to be the list. But that's going to be a problem for Mailman 2 as well AFAICS. His basic problem is that he chooses to operate with only one From address that is reliably deliverable in the current Internet, and unfortuately that's his personal address. One solution I can think of would be to send the administrative list traffic out through Gmail's SMTP gateway using his registered cufsalumni-* accounts. That might work well -- it's Postfix's job so Mailman doesn't need to know about it, those should be infrequent at best, and they won't be relays from 3rd parties as mailing list posts usually are. Dunno what's going on with his web configuration, tho. -- GNU Mailman consultant (installation, migration, customization) Sirius Open Source https://www.siriusopensource.com/ Software systems consulting in Europe, North America, and Japan _______________________________________________ Mailman-users mailing list -- [email protected] To unsubscribe send an email to [email protected] https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/ Archived at: https://lists.mailman3.org/archives/list/[email protected]/message/DWOYRX2SG7FAOV2QJ6SZR4KFHDZILQF7/ This message sent to [email protected]
