I saw this post, and this is what has been happeneing to me.. I have just bought my first apple product, inputed my btyahoo mail info and it started collecting my mail etc.. no probs... then all of a sudden 4 days ago NOTHING !! all stopped, no incoming mail at all.. no matter what I do, It wont work. I am really frustrated and rather disappointed...
And this may seem a very obvious question to you, but how do I check with my ISP about these setting you mention?
Many Thanks for any help
