Unable to communicate securely with the peer
Solved

Hello.
I've been using Thunderbird without problems for years, but I've just discovered that one of my accounts can no longer send emails.
When I try to send an email, I get this error message:
Message sending failed.
Unable to communicate securely with the peer: the requested domain name does not match the server certificate.
The configuration related to smtp.gmx.com needs to be corrected.
Does anyone know how to troubleshoot this?
Best regards.

Hello @Lorstrogoth
Make sure your outgoing server is set according to this:
https://support.gmx.fr/pop-imap/imap/windowsmailapp.html
Or change the outgoing server and use Gmail's outgoing server for example.
