It seems you like them for purposes having to do with automation, rather than that they help you read the messages. This is clearly a job for the List-Id header. The fact that it broke once when a major change was being made to the mailing list is not a reason to prefer subject filtering over list-id filtering; your filter would have broken if the [P-U] prefix had been in use for a while and then it was changed to [pfx]. It is no different. The list-id is intended to remain constant, if not for the life of the list, at least it should only change when major changes are necessary anyway. > The old server had: > List-Id: Postfix users <postfix-users@postfix.org> > > The new one has: > List-Id: "For discussions about using Postfix: questions, problem reports, > or feature requests.

This may have been an intentional change to conform to RFC 2919 for List-Id: The list identifier will, in most cases, appear like a host name in a domain of the list owner. > RobertC Additionally, every MUA that I know of recognizes a subject beginning with "Re:" or "RE:" and when replying avoids duplicating this in the reply subject. While I have used mutt exclusively for a long time to send email, I occasionally use other programs for reading. I just checked both Thunderbird and Evolution (and mutt), and none of them recognize "[prefix] Re:", so unless the person replying realizes it and manually adjusts the subject, the subject will keep growing with each reply. I have not heard of any MUA that recognizes "[prefix] Re:", but that doesn't mean there aren't any. Please, please, _please_ remove the subject prefix. ...Marvin _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
