Lately (as prophesied), there have been a number of very short spams arriving, containing only a singleton URL. My proxy's classifier was giving these an "unsure" rating -- too few clues. But, these buggers were starting to become quite annoying... So today I added a simple web-crawler, which will venture out on demand and slurp the words off any site. This little hoover is only unleashed when the number of distinct clues/words in an email is less than 150, it's heading for the "unsure" bucket, and we find an http URL in there. The entire source HTML is then whacked through the tokenizer and classified. The extra servlet processing can take a couple seconds, mostly network overhead, and really only noticeable when paying close attention to message download times, but the results are really worth it! It nails them dead. Cheers! Richard
