I believe Mutt's threading algorithm is based on this technique but I could be horribly wrong. His 5th step is If any two members of the root set have the same subject, merge them. This is so that messages which don't have References headers at all still get threaded (to the extent possible, at least.) Read the rest of that step for exactly how to thread based on 'Subject:' -- the test for truth is still quicker than the addition

I actually got bit by this last month, as Mr Cantrell had started more than one thread with the subject books and pine's very immature threading couldn't cope.

Perhaps one could modify the algorithm so that if the mails were, say, more than a day apart. Or both without 'Re:' then it wouldn't group them. Simon Cozens has written a pure Perl implementation of JWZ's threading algorithm but I can't test it cos it relies on a later version of Mail::Mbox which in turn requires Perl 5.6.1 which I don't have. I suppose I could upgrade the Perl on my colo to 5.6.1 but I'm not sure if I could be arsed. Simon -- the test for truth is still quicker than the addition

All other things being equal, I'd suggest upgrading it to 5.8.0, given that 5.8.x is actively being maintained, and 5.8.0 isn't slow if you don't have a UTF8 locale. Nicholas Clark
