Cannot connect to ATT Mail using IMAP

I was unable to send emails from TBird version 91.7.0, so I removed TBird, rebooted and reinstalled it again. I know about the ATT secure mail key/initial password, so that is not an issue.

The problem is that when I go through the TBird setup procedure, it connects, but using only POP3. IMAP is not a choice., and I need IMAP to sync our accounts into TBird on the PCs.

When I try to use manual setup, and the IMAP port 993 it will not work.

Do I need to remove my name from TBird somehow - if so, how to do it?

Chosen solution

Enter the correct Hostnames, imap.mail.att.net and smtp.mail.att.net, and set the authentication to normal password.

All outgoing settings are correct, Thunderbird still cannot send emails.

Receiving is fine, once I got past ATT's Secure Mail Key protocol. Maybe there is now a secure mail key on outgoing also? Never existed before.

Logging on thru a browser works fine, it can even see drafts created in T'Bird, that I can then mail, but wife and I really miss T'Bird, as it much better to use.

When I called ATT, knowledge of the folks on the phone varies from non-existant to better, but none of the 4 reps I talked to was able to fix the problem.

Could use some help, please.

The outgoing should apply the same key used for the incoming. Check Saved Passwords in Preferences and delete any obsolete entries. Disable a VPN if you have one and exclude the profile folder from antivirus scanning. Post a picture or description of the error when sending.
