Thanks Rick, I believe it. IMail's context filtering is lousy, but after very little tuning out of the box, we're seeing significant results on our spam detection and filtering.
The main problem we're seeing is false positives on SPAMHEADERS, BADHEADERS and SPAMCOP, but the OS databases are filtering out at least 80% of our spam. BTW, any interest in adding email categorization (based on content) or summarization algorithm?. Categorization might be another excellent method of filtering, rather than exact words. The main problem would be the maintenance of a taxonomy to determine the set of words that defines a category. We have a bit of experience with this if you're interested. We're also interested in the potential of image-based filtering via object pattern matching...another way of detecting objectionable content via processing the images referenced in HTML-based emails. Thanks for the help and for making such a wonderful product for IMail servers!
