Mutt will only thread when the 'child' messages > subject has "Re:" at the front (or whatever matches that regular > expression). Mutt's threading isn't primarily based on subject line. The proper way to determine threads is to look at the Message-IDs in the In-Reply-To: header. Mutt does also have an option (set by default) to also do some pseudo-threading based on subject; see $strict_threads and $reply_regexp in the "fine" manual. Messages that have been threaded based on the subject will have a "*" in the thread tree. If you reply to the message using mutt or any mailer which preserves the In-Reply-To header, even if you edit out that 'Re: ' prefix, it will still thread the reply correctly. However, if you send a new message with the same subject line, it won't. But either way, the intent is to group replies to a message together, rather than grouping all messages with the same subject together in one thread. w
