I see no reason why a mailing list exploder would ever be considered an "author". A cron script which generates an email as part of its routine reporting is an "author". A network monitoring service that generates an email as part of ongoing monitoring is an "author". The mailing list exploder might be considered an "agent", in the sense of being a third party who interfe… sorry, participates in the distribution process. Thus according to the RFC, Mailman nominates itself* (or rather, the pseudonym it uses when distributing messages to list recipients) as the sender: i.e., Mailman has the same role as the secretary in the defining example of the use of the "Sender" header. My interpretation of this RFC is that if I was to hand-write a message and my computer was to transcribe my scrawl to an email, I would be represented in the "From" field while my computer would by rights nominate itself in the "Sender" header. But it still stands that Apple Mail will respond "as expected by the author" when the Reply-To field is set. Where I am still confused is what would be the expected behaviour when the responder's mail client respects both the Reply-To and List-Post headers. That discussion is most certainly off-topic for this list (as if 'expected behaviour of a mailing list exploder' isn't already off topic enough ;) Alex * don't anthropomorphise objects. They hate it when you do that. _______________________________________________ MacOSX-admin mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-admin
