If you didn't change your account setup, it sounds like the BT mail server has a problem or at least the mail server's "log on" server. 

 

I have RoadRunner (in the US) and occasionally I'll get a similar error and it's because RoadRunner is having a problem (even tho they never admit to any problems).  The problem always goes away by itself.

Thanks Fireberd

Its working now, wiether it was as you said, or the fact I re-played the BT internet hub installation disk?, but Iam mad the guy told me to call out an engineer!

 

Cheers
