Hello, In most of my folders I use the following config:
set strict_threads = yes set sort = threads set sort_aux = last-date-received I save outgoing replies in the same folder as the incoming message so a discussion should show as a proper thread (and most do). However, I recently noticed a number of messages weren't properly threaded. Replies from person B to mails from me would show up as a thread, but replies from myself to person B would start a new thread every time. If I unset strict_threads the mails do show up as one thread, but my mails are shown as -*>. If I manually thread all the messages together using the & key it will show the thread correctly, but if I change to another folder and back the threads will be broken again. All the messages have Message-ID's and References or In-Reply-To headers which all seem to be correct. However, the Message-ID's from person B do look a bit odd: Message-ID: <[EMAIL PROTECTED]@example.com> I've replaced the real domain name with example.com to protect my client's identity, but the rest of the Message-ID is from the real mail. Can it be that Mutt doesn't recognise that Message-ID as a real one and ignores it for threading purposes? If so, is there anything I can do (except editing the messages by hand ofcourse) to make Mutt thread them properly again? For completeness, I'm using Mutt 1.5.17+20080114 (2008-01-14) (a Debian version). Regards, Vincent van Leeuwen Media Design - http://www.mediadesign.nl/
