Bayesian just about holding back the spam....

Hi chaps,

I guess this comes up a couple of times a day, but in the last few days,
its only been the Bayesian filtering that has stopped a torrent of spam
being delivered to my users.

On the following email, its a blatant oem software spam, but the regular
rules would not have scored it above 5, without bayes.

I am using rules_du_jour to update the rules, with a config that I have
pasted at the bottom of the screen, and it includes the SARE_OEM
ruleset; (A couple of months ago, I a sure a spam like this would have
hit 25 or something on the basic rules....)

Any ideas what I am doing wrong?

Thanks,

Tom H
