Pauls response to your message has: References: <[EMAIL PROTECTED]> and X-Mailer: Microsoft Outlook 8.5, Build 4.71.2173.0 So, while the References doesn't contain more then one, it still does have a references header. This is what I (should) have on this mail (Gnus): References: <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> I don't understand why Paul's setup works, when most of the time it doesn't... Or perhaps my mail2news gateway is adding the reference header? That seems extremely unlikely to me though. I don't think the gateway has enough information to do it. That message had the following id: <[EMAIL PROTECTED]> Keith> You could make an argument that threading by subject only Keith> is OK, since when subject lines are changed, that often Keith> means the writer is wanting to start a new thread; under Keith> Netscape, with no direct access to headers, he could not do Keith> it. Under Pine, etc., I guess you can. Threading by subject makes it hard to do certain actions, eg get all messages this one references, or highlight all responses to particular message. At least, both of these are possible with Gnus. Keith> It is certainly inexcusable for Outlook to ignore Keith> References, as well as not give any option for providing Keith> them.

Not only that, but outlook by default has a "non-standard" mechanism for quoting messages (as mentioned elsewhere). Often I get replies from people who just insert their text within my text, and I tend to miss it. Yuck. Not to mention replying to it... As for terminating threads, Gnus has an option to treat a different subject line as a new thread. This is without removing the references heading, so people can still refer to the original message, as required. So... people really need to remember to change the subject line if the topic changes (like I did with this thread). -- Brian May <[EMAIL PROTECTED]>
