Rated 5 out of 5 stars
Works so well that I am loath to upgrade to TB 3 unless I can take Spamato along too.
Unlike some of the other reviewers I have never experienced any memory problems, and I find Spamato's detection to be far more accurate than any other antispam.
Remember that if you don't like the way Spamato does something (for example the sound), you can change it on the configuration page. You can also add trusted or non-trusted domains to improve the accuracy.
