I call back the settings for all your accounts are condign increasingly complex, with all the alien advice, that I'd suggest you lot create a new profile, and add one account with the AT&T recommended settings, and utilize a secure mail key in place of the regular account countersign. Ostend that the business relationship can send and receive, then add together another account once the outset one is working. Give each account a distinct Account Proper name, and each smtp a distinct Description. Have each account send through an smtp server which has the same User Name and password (post key) as the incoming account. (Select the account in the left pane of Business relationship Settings, set the smtp in Outgoing Server (SMTP) in the right pane).
Once you accept ii accounts working properly, add the residual in the same manner. Later on, y'all tin can ever transfer data such as Local Folders, address books etc. from the old profile to the new 1. Help/Troubleshooting Information, about:profiles to create and launch multiple profiles.

I ask this considering I cannot find any departure in settings between the working addresses and the failing-to-work address. Hmmmm, Bruce

perhaps iv accounts are in a western US cluster of servers and the other is in an eastern states one. Connecting to a server proper name at a large provider is non a one to i relationship. the load balancer could dump your connection on any of a number of machines. If 1 is wrongly configured or updated ahead of the remainder, then you will encounter unlike results with identical settings.
Have you tried checking on spider web mail that the account is actually active? I have received some truly weird mistake messages over the years when the provider suspends the account for some reason.

There was an upshot some months ago I remember where 'mailbox unavailable' appeared when the sending account had a Reply-to Address in Account Settings that was different from the sending address (which information technology usually is). The Reply-to Address wasn't 'authorized' on the provider's webmail site. A possible gene here?

There is also this light-headed Yahoo push to remove less secure apps and enforce app passwords.
Try changing the server proper name in outgoing servers (SMTP) from the ATT provided one of outbound.att.cyberspace to smtp.mail service.yahoo.com authentication method in outgoing servers (SMTP) to oAuth2.0.
I would not suggest the change, except in another thread here this calendar week, yahoo support told an ATT client that was having document issues to change the incoming server name from the ATT one to the yahoo one, and so if it works for incoming, it virtually likely works for outgoing. No damage in trying anyway.
If that works, perchance consider using the yahoo server settings for the incoming equally well, that fashion you tin employ oAuth2.0 authentication for everything and the whole email mess becomes simpler.

Dearest SF, Thanks for the data. I spent awhile wandering effectually my webmail site, merely couldn't observe anything that was a "Reply to" selection. I don't think that is the problem, because all 5 of my accounts (the iv working ones and one malfunctioning) all have the same, greyed-out lettering saying the exact same thing: "Recipients will reply to this other address".
And for Matt, YOur patience with me is impressive! I tried changing the server name and authentication method but am pitiful to report the same error bulletin still pops us when I try to send, or receive messages from my troubled account. Bruce

I think the settings for all your accounts are condign increasingly circuitous, with all the conflicting advice, that I'd suggest you create a new contour, and add one business relationship with the AT&T recommended settings, and use a secure mail key in identify of the regular account password.

And then yesterday I became concerned after listening to a fraud effect on the BBC radio and decided I should change my GMail password, which I did. Since yesterday I now get my emails from GMail on my iPhone (which was always the example) simply Thunderbird repeatedly asks me to enter the countersign, and then says "Post server pop.gmail.com responded: Username and countersign not accepted." I have tried removing the TB account and re-adding it. I have tried various Port numbers every bit more ane are indicated. Also re-changing my Google single sign-in countersign. What else should I do please? Your advice will be much appreciated. Geoff (in Kent United kingdom of great britain and northern ireland)

Logon to webmail account - whatsoever password gets you access is the aforementioned password you employ in Thunderbird.
In webmail account you need to select the choice to apply 'less secure apps' or Gmail will deliberately block you.
Check Thunderbird does have the right countersign and user proper name. Username will be the total gmail email address.
Menu app icon > Options > Options > Security > 'Passwords' tab click on 'Saved Passwords' click on 'Prove Passwords' It should have ii lines for gmail, mailbox and smtp. You can edit past right clicking on each line and selecting eg: Edit Password. click on 'Close' when finished

Google are going to remove the less secure apps pick entirely. They will be starting this in June with g-suite.
So I doubtfulness they will react at all. Thunderbird however does demand to react, so folks can still access their mail service without the setting.
