AT&T POP/IMAP password issues
Just finished two hours with AT&T customer Level 2 support. Simply trying to find out why my password would get rejected with the Mac OS X Mail application and not my iphone or webmail. They were clueless and offerred to provide fee based solution instead. Well there were some threads on here that helped me correct the issue. Simply reset your AT&T email account password and that's it. Now they all work fine. Hopefully this post helps someone avoid dealing with their customer support in the future. Just reset your email password, that's about it.
Pretty much all sorts of Macs, Mac OS X (10.5.2), You name it, I've run it.
