This is a very common sendmail problem. Checking Google for:

	config error: mail loops back to me (MX problem?) 


Results 1 - 10 of about 84,800 for config error: mail loops back to me (MX
problem?). (0.45 seconds) 

This found link is one of many that will give you the answer: 

Just a hopefully polite hint that it's sometimes quicker and easier to
Google for the error message than to post to the list :)

Have a good weekend,
