Since my update to Ubuntu 24.04.01 I experience issues in the thunderbird app with sending and saving messages as a draft. The error message is always only "sending of the message failed". I already tried all the points of your support website: https://support.mozilla.org/en-US/kb/cannot-send-messages#w_verify-that-your-mail-server-supports-the-minimum-version-of-tls, but this unfortunately didn't help. I also deinstalled and reinstalled thunderbird via snap. But the problem remains. My Ubuntu is version: 24.04.01 LTS My Thunderbird is version: Thunderbird 128.2.0esr I got no firewall and no antivirus software. Everything else is in the screenshot. I hope you can help me! Thanks already!
