It's hard to tell how gmail filters its spam. I bet it's an "Intellectual Property" of theirs. However, you might get a clue if you run the problematic email through spamassassin (use 'spamc -R < your_email') and see which spam tests are being hit. If you don't have a working spamassassin configuration, send the file to me, I'll do it for you. --yuval
