I suspect, as you do, that sort by Date Just testing sending replies is not a full test. You really need to check the full headers of the messages, as reported by Rootsweb. To be a "formal" reply, the reply message References: ... header should contain a chain of message IDs, AND the (last) message ID (in a chain if reply to reply) must be in the Message-ID: ... header of the immediate parent message. Possibly some clients are not copying Message-ID to References, which will break formal threading. Threading performed by Subject: can be broken based upon how the subject is manipulated by clients and mailing list software. Consider the subject line for this reply: Re:[TMG] Re: Hidden display of some replies to posts, use: Show Replies by Date Note the double "Re:" The original subject line "Hidden display of some replies to posts, use: Show Replies by Date" is what was seen by the first person replying, and their client prefaced that with "Re: "... But THEN the mailing list prefaced that with "[TMG] " when relaying the message. My mail client then saw "[TMG] Re: Hidden..." as a NEW subject, and prefaced that with another "Re:" -- normally, mail clients will ignore LEADING "Re:" when one replies, so one doesn't get multiple "Re:" prefixes., but the insertion of "[TMG]" by the list breaks "reply" grouping. Ideally, your Message-ID ( <[email protected]> ) has been appended to the References list ( <[email protected]> <[email protected]om> ) of this reply to provide formal threading. {I'm test driving the Pandora mail client which is still under development as a replacement for Eudora, so there are still quirks in behavior.} >does not depend just on the formal threading but displays by subject >too.
