Maybe OT, but thought I'd ask - Certificate in Thunderbird

It could be that the root certificate used for signing the site's
certificate isn't in TBird's certificate store.

Go to Tools->Options->Advanced, and go to the Certificates tab, click on
View Certificates... from there you can do many things.

You might be able to download from the site you are accessing, the root
certificate used for signing the cert of your server... and import it
into the Authorities section.

Or you can import the certificate from your server directly in the
"Servers" section, then select it, then "Edit Trust"... to make it trusted.
