IMHO, receiving a few spams a day is a good indication that you are not suffering from false positives.

We have doctors and lawyers on our system; they talk about drugs, illegal activities and other topics that in many systems are likely to get flagged as spam. That's not acceptable, so we have to be very careful about anti-spam configrations.

If you read the RDJ documentation, you will see that there are a lot of rules in the form "Rule0, Rule1, Rule2, Rule3", where the base rule checks for the same thing, but the higher the number the more messages will be flagged as spam and the greater the likelihood of false positives. We don't use anything higher than a 1, but many systems use 2s and a few 3s with few false positives. With our customers, we can't do that. YMMV of course. :-)

All the best,
Mark
