I'm wondering if it might have something to do with the "Use Post Time" setting. The default is set to use the time stamp when the messages are imported, which means that all of the posts at the time of import have the same time stamp. I changed it to use the original post time, thinking that posts with the same title and same timestamp might somehow be throwing off the threading. I'll test this and see how it works. Any idea though why the posts are threading correctly?

The threading works by checking references in the headers. All the email clients I have used set this field in the header correctly. Although I have not checked, but I am pretty sure that is the requirement set out by the RFC for the email clients. Could you please post the headers of the messages that are not threaded correctly?
