Spam Spell Checker

Here’s a freebie idea to anyone that wants it. Most of the spam that sneaks into my inbox past SpamAssassin and my Bayesian spam filter gets there because almost every word in the message is intentionally misspelled. By not giving the filter recognizable content, the messages get past. So how about a spam filter that works by spell check? If more than 50% of the words are misspelled, there’s a good bet that the message is spam or in a language I can’t read anyway.
