What does "Error message mail transport server 452-452 4.1.1 temporary failure" mean?

I am trying to send a simple 5 paragraph text email (no attachments) to 66 receipients.  Everytime I try to send the email I get the message, "Message can not be send.  Error message mail transport server 452-452 4.1.1 temporary failure."  I spent 40 minutes on the phone with a technicialn from advanced technical support.  He could not tell me what the error message meant nor could he fix the problem.  Any ideas out there?

One or more of the email addresses you are sending to have a problem.  Check the addresses to make sure they are correct.

Shouldn't the system highlight which email address is the problem?

I went one by one through the 66 email receipients and found the one bad email address.  Removed it and the message went through fine.  The bad email appears to be a legitimate address, so I don't know what the problem is with it.  In the past I would get notifications from the system saying mail was undeliverable to a particular address.  I never received any such notification with this email.  Sad how the advanced tech support agent I spoke with on the phone had no idea what the problem was or how to fix it.
