Watch now as Mark goes on a rant against Yahoo....

I found the problem with J's group. Those messages that weren't threading were coming from Yahoo. They were replies. But the only References header had the Message-ID of that message. But not quite. They added a '.ref' to the middle of that id. Why? WHO THE HELL KNOWS! And it doesn't include the Message-ID of the message it's a reply to. WTF.

We handle the case where the only References ID is the message's own Message-ID. But the extra '.ref' screwed that up, and prevented the rest of the algorithm from working correctly.

We're now handling this correctly. For those keeping track of these things at home, we had a similar problem a year or two ago with Yahoo, except instead of '.ref', they were adding ''. I had blissfully forgotten about that, much in the same way I try to forget about the pain of having cavities filled.

Ahem. I feel better.
