Thunderbird 128.1.0esr - "Failed to send message. Error sending message. The mail server responded: spam id=155817::1723829084-40E2144E-91888C35/29/1527808. Please check the message and try again."
Thunderbird no longer sends emails from my standard account. Receiving continues to work without any problems. The provider is Vodafone with the .kabelmail.de address Screenshots show the settings. Otherwise these always worked. I've already set the TLS version to 1 in Thunderbird, without success.
The error message can be seen in German on the other screenshot and means in English:
"Failed to send message. Error sending message. The mail server responded: spam id=155817::1723829084-40E2144E-91888C35/29/1527808. Please check the message and try again."
