Hi,
We've been looking and trialling No Spam Today which is based upon spamassasin. When we first tried it, it was catching probably 99% of all spam. However, over the past three months this figure has decreased noticeably. It appears to be because spammers are spelling words incorrectly - sometimes completely misspelled but recognisable to a human reader.
Does this call into doubt the validity of word/phrase blocking as used in spamassasin?
Regards, Rob.
