If your service is via a BT adsl circuit change your log username to [email protected]_domain (no password needed). If you are I.P you will connect (but you cant surf) if datastream you will not connect.
Thanks Daveboy. I tried this and it look as though I'm on Datastream which is a pain as I want to migrate to an ISP using IP. I think I started on IP. Can ISP's move you to datastream without telling you? It seem anti-competitive to me if it makes it impossible to migrate.
