5.7.0 (#AUTH005) Too many bad auth attempts

Hello @bgollop, we understand how important it is for you to be able to send emails, and we are here to assist.

To use your email client, you need these server settings, which work for both POP3 and IMAP emails.

Also, due to recent security upgrades, you may need to update your settings. Learn more about the security upgrade.

If your email program or app is affected, you will need to create a secure mail key so you can keep receiving and sending your AT&T email.

A Secure Mail Key is a 16 character password that you will set up and use instead of your regular password, and this is required in order for your email to work properly.

To create a Secure Mail Key:

1. Access att.com.
2. In the upper-right corner, select the Person icon. 
3. Select View Profile > Sign-In Info. 
4. Under Secure Mail Key, select Manage Secure Mail Key.
   • If there are multiple email addresses linked, please select the email address you want to use.
5. Select Add Secure Mail Key.
6. Enter a nickname for the secure mail key and select Create Secure Mail Key.
7. Select Copy Secure Mail Key to the clipboard. 
   • For security purposes, the secure mail key only displays until you select OK.
   • If you lose or forget the secure mail key, you can create additional secure mail keys, as needed.
8. Select OK. A confirmation will display and you will see all the secure mail keys created.
9. In your email application, replace the existing password(s):
   • For POP, delete the existing password. Enter or paste the secure mail key in its place.
   • For IMAP, delete the existing password for both the IMAP and SMTP servers and replace them with the secure mail key.

Let us know if the steps above help, or if you would like additional assistance.
