Hello, after updating the last version 128.10.0 I cannot send emails anymore. I read online about possible solutions, nothing worked. I have an updated Windows 11, my provider is KPN (Telfort). Telfort is a company that has been taken over by KPN, but I can still use my Telfort email address and smtp.telfort.nl as smtp address. That has not changed. I tried several adjustment for the smtp adrress, but the problem remained. 

 I hope you can help me, thank you.

I solved the problem by deleting a second account in Thunderbird. Appearantly that account disrupted my main account
