ATT / SBCGlobal Email Account Setup in an Email Client

Server settings for IMAP (from Thunderbird but they probably work for all clients): ... 993 ... SSL/TLS ... Normal password ... 587 ... STARTTLS ... Normal password

In March 2021, a client’s Mac Mail became unable to access SBCGlobal email for an unknown reason.

First, because we had made some failed attempts to get into the webmail at ATT.NET, the account locked us out. The lockout appears to last indefinitely: it doesn’t clear itself. We needed ATT tech support (877-285-0144) to give us a temporary 6-digit password to use to log in to the webmail account at ATT.NET. Upon login, the system required creation of a new permanent password. That new password worked for logging in at ATT.NET, but it didn’t work in Thunderbird. However, although the ATT rep said that the secure mail key wouldn’t solve the Thunderbird problem, Thunderbird succeeded with the secure mail key as the password. Apparently ATT uses custom account security that resembles OAuth (or is OAuth, implemented uniquely). At least some reps don’t know this.

Security keys are listed in the customer’s account profile at ATT.COM (not ATT.NET). In the upper right, click ACCOUNT then MANAGE PROFILE. At the bottom of the profile page under MY LINKED ACCOUNTS, click MANAGE SECURE MAIL KEY. A customer account can have many security keys. Each instance of each email client requires its own key, and key is usable only once. The format is 16 lower-case letters. Once a key is created and revealed, for security it can’t be read again by the customer: only deleted if desired. (Also, the system won’t allow the key itself to be used in the key’s nickname field.)

ATT’s note in this section is: You may have to use a secure mail key to access your AT&T email with some email applications. To change a secure mail key, just delete it and add a new one.

That covers the basics. Note that in iPhone Mail (and maybe in other email programs), trying to enter a new password for a previously installed account may not work. On an iPhone, an attempt for ATT brought up the standard OAuth login window (which is typical for Gmail and other email providers), but it refused the password (security key) repeatedly. I deleted the ATT email account from the iPhone, then re-added it from scratch; this technique succeeded and didn’t bring up an OAuth login window (whose appearance for an ATT email account may be a strong indication that login failure awaits).


To email an EXE file: copy the EXE file, change the copy’s suffix to JPG, and add this to the file’s name:



     original: Handy.EXE

Then either...
7z Option: Use 7-Zip to copy the altered file into a new password-protected 7z archive (folder). Don't encrypt the file names within it.* Email the folder. The recipient should have 7-Zip installed and use it to access the folder. In the extracted folder, change the file’s suffix from JPG to EXE, then run it.
ZIP Option: Use 7-Zip to copy the altered file into a new password-protected ZIP folder. Email the folder. The recipient should have 7-Zip installed and use it to extract the folder. In the extracted folder, change the file’s suffix from JPG to EXE, then run it.
*Gmail accepts encrypted 7z attachments only if the filenames are unencrypted. Gmail insists on seeing the file types inside but can't tell whether the types are fudged, as they are in the methods above.
• For email in general, the larger the attachment, the longer the delivery time. Example: an email with a 23-MB attachment took 5 minutes to arrive.
