Good point, something I had overlooked. I used to have (on Antigen) Spamhaus and Spamcop set up, where on Exchange do I enter these RBL lists?

Found it, just need to add some info now. Before I just used to add xbl.spamhaus.org (eg) what's the syntax for doing it now, I notice there is a Provider Name and look up Domain section.

I have implemented 3 RBL lists:
bl.spamcop.net
rbl.spamhaus.org
xbl.spamhaus.org
Are these the correct URL's to use?
bl.spamcop.net
rbl.spamhaus.org
xbl.spamhaus.org
Are these the correct URL's to use?

I was getting a lot of legitimate mail blocked using those three RBL providers, do you have a recommendation to a good one I should use?
