Interesting - I wouldn't have thought they would have any message-id. Could you pick a random Exchange (good) mail, and send me a copy of the message id header for that message? Maybe there's an Exchange format for the things that we can leverage. If that's done, and once the From:none fix is in a released version, that should help about as much as possible, probably. > Should we look into the configuration of our Exchange server > because it seems to me that abnormalities of the mails coming > from our server are circumventing your program from doing > from what I think it does normally perfectly well. I'm not sure about that. One of the problems is that empty messages are ones that SpamBayes has the most trouble with, simply because there are no clues, so whatever is there will influence the final score quite a bit. That Exchange-only messages don't have regular headers make things worse, because there are even fewer clues. The from:none problem was our fault, I believe (in any case, it should be fixed in the next version). I'm not sure what the story with the message-id headers are - that may be your Exchange server doing something odd (although Exchange itself may be more at fault than your configuration). =Tony.Meyer -- Please always include the list ([EMAIL PROTECTED]) in your replies (reply-all), and please don't send me personal mail about SpamBayes. http://www.massey.ac.nz/~tameyer/writing/reply_all.html explains this. _______________________________________________ [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/spambayes Check the FAQ before asking: http://spambayes.sf.net/faq.html
