TREND IMSS content filtering piece isnt working for keywords

Even when I reduce the Body keyword expressions to a single file, with a single word in it, and test it, it doesnt catch that word, but worse, it catches other, random emails without that word in it.

Same result whether I test for keywords in subject or message body.

All the other policies for spam / phishing etc. work ok.

Keywords such as "viagra" would be nice to catch as another line of defence.

Anyone heard of this bug before?  Suggestions welcome.

Odd.  Most of the necessary keywords (viagra included) should be quarantined by the spyware definitions downloaded from TrendMicro.  Are you running updates?

TrendMicro recommends you configure the product to update every 15 minutes, as this is how frequently they often release new SPAM definitions.  I've found that if I don't update this frequently, more junk gets through than it otherwise would.

Page1985 - The spam / phishing piece analyses certain email bits and comes up with a "rating" - I've set our detection threshold to 4.0 - anything less than this starts getting hairy on the false positives.

I don't think this would catch a message from my gmail account that simply said subject: test, data: viagra, for example - but I don't know how it calculates the score.

I'm looking to trap just a few racist / sexist / spamist / basic profanity words which don't appear to get trapped with above rule.

Updates are running every day - did have it set more often but traffic get's a little on the large side.

I've recreated policy and this appears to work now - maybe policy was corrupt.  Anyway - will close.
