Just to revise and extend my remarks...I think it is a mistake to overload the subject-tag feature in the way you suggested. Since there's no ironclad guarantee that a subject line beginning with "[something]" is always list mail, you really can't predicate OOO behavior on it. If you're not doing the evaluation on MAIL FROM:, then you should be doing it based on something like Precedence:. (For instance, OOO should never be sent back if Precedence: is "junk", either.) It could be some other header, of course, but this one is available for any MUA author who wants to implement its use. Anyway...my $0.02. Nathan
