I've been using Thunderbird for ages without any (real) problems. A few days ago, Thunderbird updated to version 78.5.0. Shortly thereafter the problems started. I can't remember if it started immediately after the update so I'm not sure if the update was the direct cause.
Anyway, every time I try to retrieve my mail (by clicking "Get Messages") a pop-up appears:
(See image attachment)
This pop-up isn't new to me since I'm using my own mail server with a self-signed certificate. So every time I update the certificate, I get this popup. It is new however the pop-up appears while nothing has changed (other than Thunderbird updating).
If I click "Confirm Security Exception", the popup disappears but no mail is retrieved. If I click "Get Messages" again, the pop-up reappears. Oddly enough, If I go to Thunderbird's Certificate Manager, I see the certificate was actually added.
So that's one strange thing. It isn't the strangest thing however. What's even stranger is that the location (email.glasshouse.nl:995) isn't the address of my mail server. If I look under Thunderbird's "Server Settings", I see the correct address. Even if I change the server address to something else (the IP address for instance), the pop-up still displays email.glasshouse.nl as location. I'm not worried this is some kind of hack or virus or malware since I recognize the address - it's the mail server I used well over ten years ago (in Thunderbird).
So what is actually going on here? And more important, how can I solve this so I can get to my email again?
Thanks in advance!
