Hi, I have recently switched ISPs from Virgin to BT.com. I'm currently using BT's Yahoo email, which is of course, web-based. I have tried to get Thunderbird (my favourite), Eudora and Opera to work with my BT Yahoo email, as I would like a client that I can work with offline. None of the foregoing programs will work and I can't understand why. Contacted BT and they just told me to use their server settings: 'mail.btinternet.com' for both outgoing and incoming mail, but they don't work at all. Any ideas on this one folks? BT did not have a further answer. Many thanks in advance. David.
