I use Thunderbird for more than 15 years and I've never had a problem. But since April 1th several e-mailaccounts won't import e-mails anymore. On my phone with another client the mails come in, but in Thunderbird, nothing happens. I won't get a pop up or anything. Nothing happens. I see an error in the console (See attachment). 1 of the e-mailacounts is from a website with a active SSL certificate. The others aren't private domains but with no active website or ssl certificate. I've googled the error, I uninstalled Thunderbird en re-installed it again. I alsof find a possible solution somewhere with a new string in config editor and a new exception at the certificates. But nothing helps... Can someone help me or tell me what I'm doing wrong? 2 accounts ar related to my business and I really need those in Thunderbird. Thanks a lot!!
