Dear Maintainer,

Thunderbird does not work with the certificate from w00596df.kasserver.com even it is a
valid certificate. When I try to added the certificate as an exception thunderbird disable
this option in the certificate management.
With this I can not get a connection to the mailserver. I observed this more or less since
the last update of thunderbird.

This behaviour does not happend with other email programs like Apple Mail.

Thanks in advance
Norbert

Hello Norbert,

this is an upstream issue in my eyes.
We don't change any upstream code regarding certificate handling.

You can follow these steps anyway, maybe some AddOn is responsible for
the seen behavior.

https://wiki.debian.org/Thunderbird#Bug_Reporting_.2F_Issues

The last paragraph there is mention the possibility to use upstream
binary packages, please try this also out.
If the issue is still existing please open an issue in the Mozilla
bugtracker.

I tested different upstream version until the last version. All have the
same error: "The certificate for w00596df.kasserver.com does not come
from a trusted source."

Regarding your advise I opened an issue in the Mozilla bugtracker
https://bugzilla.mozilla.org/show_bug.cgi?id=1940755 .

I tested the mail connection with Claws Mail as well without any issue.


Thanks!
