T-Bird thinks an email I'm sending is SPAM, how do I tell it otherwise?

I'm trying to respond to a message that came in requesting some information, I replied and filled in the data requested, clicked on send, and an Alert message popped up stating "An error occurred while sending mail. The mail server responded: This message was classified as SPAM and may not be delivered. Please check the message and try again." What do I need to do to convince T-Bird and/or the server the message is not SPAM?

This kind of rejection is from either your mail service provider (refusing to send the message) or the recipient's mail service provider (refusing to accept the message). Usually the recipient's server.

Are you sure the message was legitimate and not a phishing scam?
