Outgoing server does not support encrypted passwords
I've been using Thunderbird for months. Starting today I get a message: The Outgoing server (SMTP) smtp.myserver.com does not seem to support encrypted passwords. If you just set up the account, try changing the 'Authentication method' in 'Account settings | Outgoing server (SMTP)' to 'Normal password'. We run our own mail server and didn't make any changes. Other people in the company can send emails (using Thunderbird) but I can not. I made no changes. I simply went home last night and came back this morning. It won't let me change the account to Normal Password and send either so I'm currently dead in the water making this a critical problem. I have rebooted both the mail server and my computer. I'm currently set for port 110, startTLS, Encypted password... same as before and same as other users here.
What else can I try?

probably the password was downgraded silently in the background. I think I recall some chatter about not allowing downgrading in this scenario. I have never seen a site that required encrypted passwords. Generally the connection is encrypted (TLS, SSL/TLS or StartTLS) not the password. You might also want to check the"other mail client" is using encrypted passwords.
I suggest you have a look at this 2014 discussion. https://support.mozilla.org/en-US/questions/1018950

If I send from a different email client on this same computer it works fine. It's only Thuderbird that's puking when trying to send. Suggestions?
IF I set the SMPT password to Normal Password I can send emails. But in the past it was set to encrypted. Why am I needing to change this?

Thank you. That was helpful. In my case I own the other mail server (imail server) and haven't made any recent changes to it. I don't understand why I suddenly started getting the error in Thunderbird. Other people were not getting the error, just me. The other email program was Eudora. It's old, but it's still one of the best out there in my opinion. I don't use it any more because of the lack of security updates but I loved it's features.
Anyway, with no changes to my Thunderbird nor the mail server, I don't know why the errors. But after reading the link you sent to the 2014 conversation I feel better about the situation and will just leave it with the passwords unencrypted and let the TLS do it's job.
Thank you again.
It's interesting that different emails are being effected at different times. I have a few email accounts that are all using the same domain on the same server. I started out with a problem on only one of them, then another. This morning a third one has now picked up the same issue. This is confusing. Why did it change at all? Why did the change, whatever it was, not effect all the email accounts at the same time? There's a week between the first one being effected and the one today. It's just strange.
