I have been using Thunderbird quite happily for several months for the e.mail on my wife's business. Then today we received a pop up entitled 'Add security exception'. 'You are about to override how Thunderbird identifies this site.' 'legitimate banks, stores and other public sites will not ask you to do this.'

I have checked my pop 3 settings and they all look ok.

It seems very odd that it would suddenly do this which makes me concerned that this is a case of someone trying to hack / impersonate the server that hosts our e.mail - how do I rectify it?

The email is being run on a home pc using windows 10. E.mails are still being received on an ipad and iphone (not using thunderbird).

What is the exact error message shown in the exception prompt? You may want to post a screenshot. http://support.mozilla.org/en-US/kb/how-do-i-create-screenshot-my-problem

Can you press 'Get Certificate', and then 'View'. Please post a screenshot of the 'Certificate Viewer' window.
