Thank you! I was actually aware of that however, I had said it has the 
higher weight meaning it will be used last, but you see not all email 
systems are compliant with the rfc's and sometimes just use the first MX 
record that comes up assuming the MX with the (highest priority/lowest 
weight) will be listed first.

Thank you for your link though, I appreciate your taking the time to try 
to educate fellow IT professionals.
