The same applies to both Entourage and Outlook. The entry was written before Outlook was released (but it still stands).
It doesn't matter that you are not sending to groups. The problem is that the server sees something in your message that makes it look like a spam and blocks you.
In any case, that's an SMTP server message and you should contact your provider to figure out what can be done to avoid these warnings.

Ok, so after reading all of these posts I also discovered that one of the email addresses was invalid therefore my ISP was rejecting the email and sending the error code. Check and make sure all of the email addresses you are sending to are valid (in my case it was .com was messed up at the end of the email address). Good luck!
