Re: [SURBL-Discuss] quick poll on SURBL hit %

Just curious as to what average percent of spam people see SURBL hitting. In a non scientific manor, I average about 85% or greater hitting SURBL for all spam that doesn't get rejected by my MTA. I have a feeling if I clean up my results a bit, that number would be even higher.

This number seems correct for me too.

But what's very interesting is to note that both numbers (detection rate and false positive rate) are quite stable for everybody. This is a measure of the reliability of surbl as a filtering criteria.

Last month I was looking at the URLs hitting messages on our server during 8 months, and I found around 20000 URLs on some millions of spams.
