some senders on this maillist use a version of thunderbird that adds more then one references header and this imho breaks threading :(
Whether or not this would break threading depends on the MUA or other software doing the threading. For example, Mailman's pipermail archiver prefers In-Reply-To: over References: for threading.
Multiple References: headers is a clear violation of RFCs 2822 and 5322 (RFC 822 is not clear on this point).
It would be helpful to those who may be using this broken Thunderbird and perhaps others to know which Thunderbird version(s) has/have this bug.
I think Mark Sapiro has his postfix setup wrong, or w/e MTA he is using.
