I've got a problem with receiving mails in thunderbird. It asks every time to confirm an exception for ruggedinbox. I import the certificate and get the warning again. This warning shouldn't show up from importing the correct certificate and even after accepting the exceoptin it pop-up again and again. So I can't receive any mails within thunderbird.
Are there any suggestion?

(In a few hours I could send screenshots with preferences.)
