I attempted to log in this morning and the system prompted me to enter my Comcast email account password. I am positive I am entering it in correctly. Then, this message pops up:

Sending of username did not succeed. Mail server mail.comcast.net responded: Plaintext authentication disallowed on non-secure (SSL/TLS) connections.

How do I resolve this?

I contacted Comcast directly and found the solution. They recently changed their settings. To correct the problem, go to Thunderbird's Server Settings and change the Port from 110 to 995. Change the Security Settings on the Connection Security to SSL/TLS. Problem solved.
