I have a customer who is running a exchange server, But some emails he sends are blocked by some outside email servers, eg sorbs, He has contacted people at sorbs and they say its not there problem, But this problem also has problems with ISP email servers as well.
He has tried changing his Ip address with his ISP, and it still happens. he is running a .com in New Zealand, would this have anything to do with it?
Is there anyway I can redirect a email through a ISP proxy server??
Any ideas please post :)
