You may want to subscribe to the Declude junk mail list by sending
a message to [EMAIL PROTECTED] with "subscribe
Declude.JunkMail" in the body.

We usually process between 1,000 and 2,000 messages per day so we
are dealing with relatively low volumes.
Our spam rate is consistent at 30% and higher of total messages
during the week and about twice that on weekends.
We started using SNIFFER at the end of May. It has reduced our
false positives from about 4% of held messages to just above 1%.
Most of our false positives now are subscribed lists.

We hold, inspect, and move back any valid messages which is how we
know the % of false.
