hi all, well SB 4 is doing a good job, but i still get 75-80 spam emails a day on some accounts, so i am trying an external spam filtering service, hopefully it gets most and sb will get most of the leftovers,, here is the problem – i can see the blocked span in the control panel of the new spam service so i know the new mx records are working, i can see what is sent to my server as good emails for the domain filtered, by tailing the rejectlog, but emails for the domain are being rejected for authentication reasons– the domain being filtered is hostu.org — pasted from the tail below list the H=bolt7b.mxthunder.net [126.96.36.199] which is the filtering co. and i believe this is the problem, but where in the exim config and what should i put there to allow this filtering mail sent to be accepted,, any help is welcome and i will post any extra info you might need to help me resolve this..

it looks like *.mxthunder.net needs to relay to the server, how can this be set in the exim config to allow them to relay to my server ? thanks again for any help
