Outgoing blocked as "administrative error", but not on other services
I now get this message when trying to send from Thunderbird. I have no problem sending from my other service (MWeb). "An error occurred while sending mail. The mail server responded: Administrative prohibition. Please check the message recipient and try again."

You should contact your email provider. The message is from their server.
