Thunderbird imap connection problem

[jbrennec51]

Now that the email service is working, Thunderbird which had been working prior to the failure is failing to connect.
The failure message which may or may not make sense, "Thunderbird can't connect securely to x01.x10housting.com because the site uses a security protocol which isn't enabled."
I've reviewed mail client configurations on cpanel, all match. I've googled the error to no avail.
any help?

Gotta fix, not sure I like it, but it seems to work. Turn security settings in Thunderbird for x10 account to NEVER.
