What are my AT&T IMAP settings?

IMAP is imap.mail.att.net on port 993 (SSL); SMTP is smtp.mail.att.net on port 465. Auto-detected from your address.

What is a Secure Mail Key?

AT&T's app password for mail apps. Create one at att.com under Profile, Sign-in info, Secure mail key. Your regular AT&T password will not work over IMAP.

My address is sbcglobal.net, is that supported?

Yes. All legacy AT&T family domains (sbcglobal.net, bellsouth.net, ameritech.net, pacbell.net and more) use the same imap.mail.att.net servers.

What you need

Your AT&T address

A Secure Mail Key (required)

AT&T's version of an app password. Create it in your AT&T profile under Sign-in info, then paste it here instead of your account password.

AT&T Mail works best with a revocable app password.
