Sorry for the very late reply. I recently started using Gmail. It classified your mail as spam. (Go figure...) I just dug it out of 3000+ spams which had piled up.

Sure, the discussion can get too technical for this list at times. The recent discussions about image-based spam, ocrad, etc should have moved to the spambayes developer list but didn't. I've solicited test help from this group and discussion of the problems with the current image-based filtering have gone on here. I'll try to move such stuff to spambayes-dev sooner. Also, you're welcome to hit the 'd' key. As a subscriber you're under no obligation to read and understand (or even to care about) all discussions. Skip
