Spam detection rates

[Gareth]

I was wondering what sort of detection rates people are getting when
using Mailscanner.
Our old spamassassin 2.64 based system was only getting about 80% but
with Mailscanner and the latest software we seem to be getting over
99.5% which is extremely good. False positives are very low aswell.

We do tend to be very strict about pictures attached to emails as I
think we have a few rules which do the same sort of checks. Some
external people using the incredimail 'piece of cr**p' mail client get a
continuous score about 4.3 which leaves the AWL little room to bring the
occasional higher scoring mail back below the 5.0 threshold. It hasn't
caused any people to complain though.
