In Thunderbird on my Mac, when I select my own server to send emails the following error message appears.

Sending of the message failed.
Unable to communicate securely with peer: requested domain name does not match the server’s certificate.
The configuration related to mail.andrewscottmusic.com must be corrected.

Here's a screenshot of the error:
