issues with protonmail server
I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."
Thank you for your help!

Is the message possibly about the recipient's email address?
