You need to have the ATT.net email settings done very specifically to use the SBCGlobal email login service. Doing so is not a big deal. You just need some simple information, and you can see how easy it is to customize AT&T email settings. It might be a little difficult for you to understand the stuff the first time, and so, here I am to instruct you on how to configure the AT&T email server. No matter what sort of system you might have that supports the AT&T email login, or how you get access to the AT&T email account, but with some minor variations, the method of doing the settings is almost the same.
