Hi, noob here.

I just installed avast and then started up Thunderbird.

It now asks me to allow a security exception for "pop.gmx.net:995" and another mail adress.
I have the option to download a security certificate, but it says there isn't enough information / unknown identity.
Even if I allow the exception (and the option to safe this exception is ticked), the program keeps asking me for this exception. Nothing else happens, I can't use my Emails.

Can you guys help me? Would be very much appreciated.

Best, Mathis
