SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message.

The error means your email provider's server is not properly configured and exposes you to the LogJam attack. Thunderbird is trying to prevent that. https://weakdh.org/

As a workaround you can install this add-on. https://addons.mozilla.org/en-US/firefox/addon/disable-dhe/

Note, this will allow you to connect to the server in a secure way, but it doesn't address the underlying problem of the server still being vulnerable.

Check this article if you are having difficulties installing the add-on for Thunderbird. http://xenos-email-notes.simplesite.com/416814616
