Several years ago AT&T sent all their email account hosting to Yahoo. It's been a pain in the asp ever since. Auto-forwarding drops messages (many don't get forwarded on the intended destination), spam-filters can't be turned off (many false positives), several times the POP3/SMTP servers with expired security certificates.
Damn you AT&T for foisting your users off onto Yahoo!
Iron Curtain 2.0 with Nikita Sergeyevich Khrushchev 2.0 (aka Vladimir Vladimirovich Putin) at the helm. That may seem like an exaggeration but I really think that Vlad idolizes Nikita and want to be just like him.
