Change server name in "server settings" for yahoo account in Thunderbird from imap.mail.yahoo.com to imap.mail.att.net

Done

Why the change from imap.yahoo.com to .att.net? Is that whay Yahoo is going with now?

I have no idea. All I know is I made the change and Yahoo IMAP email via Seamonkey is working again.
I made no change to the output server: smtp.mail.yahoo.com
Maybe att.net is a temporary imap server while they are repairing the yahoo.com server.
I don't know.

Strange.

I see. Don't know if I trust to try it.
It's a bummer that I can't get into my yahoo mail via TBird though.

I just copied/pasted the att.net address where the yahoo.com sever address was in the settings for the incoming IMAP and it started working.
I didn't change anything else.

I dunno, unless my yahoo-served email address ends in att.net, I don't think I'm giving up my yahoo email password to AT&T ... What domain is your email address?

Email address has not changed. Still @yahoo.com

I'm using a *.yahoo.com email address (free account, not due to my ISP) and the change in IMAP mail servers to imap.mail.att.net worked for me. However, several folks (such as myself) noticed that the old mail servers started working again 30 minutes ago, while it didn't for leishirsute. Perhaps its based on where you live. I've updated http://kb.mozillazine.org/Yahoo to mention imap.mail.att.net as a workaround if you have problems.

The yahoo SMTP server at smtp.mail.yahoo.com still works for me. Looking at the raw message source of the received message I see that it actually used nm48.bullet.mail.gq1.yahoo.com as the smtp server.

One possible explanation for the change was that it was due to "AT&T merged with Verizon which acquired Yahoo" but that is inconsistent with Verizon migrating Verizon ISP users a while ago to AOL.

Both addresses go to yahoo.com servers. See tracert info below:

I wouldn't be surprised if att.net is an interim address.

[leishirsute]

This is possibly why att.net is working, a different route to yahoo servers and possibly bypassing a misconfigured yahoo.com imap server:
"The mail client servers you will need to use (and should have been using for at least the last couple of years) are:

POP3: inbound.att.net, SSL, port 995
IMAP: imap.mail.att.net, SSL, port 993
SMTP: outbound.att.net, SSL, port 465

The reason that AT&T created the att.net email server CNAME aliases is so that they can change their email hosting (or even return to hosting it in-house), and the customers won't have to change their email client server settings no matter what AT&T does with the customer email handling. The current CNAME aliases point to Yahoo! servers."

I haven't done anything but all seems back to normal today. Lets hope it stays that way

[BillyDick]

I was going to try the imap.mail.att.net server suggestion, but then saw therealrayf's post and, as he posted, loaded Thunderbird and emails started pouring in from both my accounts at Yahoo and Gmail.
As far as I can tell, all is back to normal.
Let's hope it stays that way!

BTW: I didn't get the "Allow apps that use less secure sign in" message when clicking on the Mail icon from My.Yahoo's front page. The security setting is set to On.
I've clicked on the icon several times while entering this reply and still no message.

[leishirsute]

I switched back to yahoo.com and it's working for me as well.
att.net must have be an alternate route that works for att customers.

I deleted account to yahoo mail but kept all the files. I also reverted to POP server/service; I still use IMAP for outgoing server but POP for incoming. I had originally had POP for incoming but followed the suggestion to move to IMAP for both incoming and outgoing. Well that was wrong. And the files for Yahoo account stayed in a yahoo.mail.pop folder--the update broke it. Just rebuilding the files didn't help me. But the files were not corrupted so I was able to re-establish mail service. They need to stop breaking Yahoo mail every time they do a larger update!!!

I might have misread the suggestion for set up; it could be when you are setting up an alternate device and mirroring/duplicating the emails rather than removing them from the server you use the other set up. I have a past of "skimming" technical stuff and reacting to key words. So, I might be spreading blame for something I did; but, I see others had the same problem.

"I still use IMAP for outgoing server but POP for incoming. "

Both IMAP and POP accounts use a SMTP server to send mail.

https://bugzilla.mozilla.org/show_bug.cgi?id=1382010 mentioned that the problem was that Thunderbird had used lower case text when specifying the type of authentication (SASL mechanism) it wanted to use. Its supposed to use upper case. Apparently the mail server had automatically converted that command to upper case before (to avoid case sensitivity problems), and for some reason stopped doing that. The patch is in Thunderbird 52.3 which is supposed to be released 2 weeks from now.
