SBC User Email Address
Before the merger with AT&T, SBC Communications offered dial-up and high-speed Internet services as well as telephone service. Users of the Internet services send and receive e-mail using the suffix "sbcglobal.net." For example, an email address is formatted as "firstname.lastname@example.org."
Email Server Address
When you configure your email client to send and receive messages on your SBC Global account, you must use mail server addresses to do so. For example, to send messages using Microsoft Outlook, Outlook Express or Windows Live Mail, you must use "smtp.sbcglobal.net" as the outgoing mail server. When this address is not properly configured, your outgoing mail is not sent.
SBC Yahoo! DSL Service
After the merger between SBC Communications and AT&T, the company's existing users gained the ability to check their Sbcglobal.net email account with Yahoo! Mail. Additionally, users' high-speed Internet service became "SBC Yahoo DSL." Therefore, after the merger, Sbcglobal.net refers to SBC Yahoo! DSL Internet service.
