I can't send emails

For some unknown reason, I can no longer send emails via Thunderbird. I can receive them just fine.

I am attaching a screen image of the two messages that pops up. The shorter one is first.

The larger message says "certificate belongs to a different site"

I am not a technical person. I did a chat with my email provider (Register.com). They said it was not their problem.

Any help appreciated.

how about you use the view button to look at the certificate you have received for the connections and see what server it is really for.

What does it say?

Hi Matt - Thanks for the reply. I tried another test email (it didn't go through). I could only access 'view' after I had written the email. I attach the screen shot of the pop up. Kris

Matt was referring to the View button in the certificate prompt you posted earlier, just below the Get Certificate button.

Thanks! When I tried to click on View - nothing happened. I will attach that image. When I got out of the email, another screen popped up. I attach that as well.
