Mine has been working just fine until today -- same problem. I think it's an apple issue -- I have mail accounts on yahoo, gmail, live, etc. and none of them work now although they've worked fine until this afternoon. I have not made any changes to my ipad2, mail app, firewall, or router or anything else. If you google this problem there are a lot of posts today -- many people having this problem...no resolutions though. Any ideas?😕
