Hi folks,

I've been using Thunderbird successfully with my Earthlink email for a couple of months (Windows 10)

Today suddenly, sending stopped working. Here's the error message:

Sending of the message failed. The Outgoing server (SMTP) smtpauth.earthlink.net does not support the selected authentication method. Please change the 'Authentication method' in 'Account Settings | Outgoing Server (SMTP)

I have the correct settings for Earthlink (STARTTLS, port 587), and sending has been fine until today.

When it first happened, I rebooted the PC and then it started working again.

Trying again later, it stopped being able to send.

Someone posted that the issue can be solved by sending and receiving insecurely, but that is not a solution!

I was also using Encrypted Password with no problem, and today that started causing an error message, forcing me to reset to Normal Password.
