I'm with Virgin media and have been for years. I can log into my account on line and send and receive no problem! Iphone as well, same email, no problem. Recently without any alteration from me, I can send emails on Thunderbird but when I go to receive it might say there are 100+ emails to download but instead will only download 1 particular email that it seems to be stuck on. Have updated everything but it will only download the same email over and over. Please advise.
