Email sending problem with Thunderbird.
I have a distribution list which I have used many many times. Today I am getting this error message: "An error occurred while sending mail. The mail server responded: GT3XnbDDjviGhGT3Yne96d internal error. AUP#SMTP." It then lists one of the email addresses I am trying to send to. If I delete that email address from the recipient list, it happens again with another email address. What's going on ???

This is the second issue I have seen here involving mailing list with the same internal error. AUP#SMTP. type of error in 24 hours.
In neither case was the mail provider apparent, a quick google makes me think it might be Shaw, but perhaps you could tell me who your mail provider you are sending through is..
Yes, my mail provider is Shaw.
