Sometimes I can send emails from my Thunderbird account, sometimes I can't. When I can't, I get an error message that claims the message could not be sent because the outgoing server timed out. What????? I already went through your entire list of "trouble shooting" items. Still won't work today. Did yesterday. Not the day before, but did the day before that. How weird!

So I just went back & tried again, and I got a whole new error message!

"An error occurred while sending mail: The mail server sent an incorrect greeting: 5.7.1 [C20] Message blocked.."

Cannot understand what is going on.
