Answer : Poor MTA? how to correct

You're blacklisted. I did a lookup on that IP address, and it looks like you're listed at five-ten for some reason:
http://www.five-ten-sg.com/blackhole.php?ip=69.73.183.93&Search=Search

By their explanation, that server has relayed spam in the past. Make sure your server is secure and not relaying and contact them to remove you from the list.
