Why does Thunderbird prompt for a security exception on a site that isn't my email server?

Thunderbird has started repeated prompting me for a security exception on a certificate supposedly issued by www.b-g.k12.ky.us (a site associated with my grandson's school system). This site is not one of my email servers. So why is Thunderbird complaining about its certificate?
