It's highly unlikely to be exchange related. It's a network problem either configuration or capacity related. TT recently cited load balancing servers not working to specification as the cause of DNS issues. In the past I can remember the same issue of load balancing software affecting the email servers. As TT are in the process of assimilating Tiscali's network, I suspect it will be related to this as well. Opal will fix the network and not tell anyone what they've done in true ISP fashion. There is no excuse for a communications company failing to keep its customers informed. But that is what they all do. As long as all their customers keep paying, they will keep on doing the same.
ps I hope that Jack's connection is still OK. I am sure he will tell us if it's not.
