"machines" do not have MX records, domains have MX records. I think you 
told your provider some wrong information and that's why they set it up 
wrong.

What you attempt to do is just stupid (no offense intended) if you do not 
want these machines to handle mail from external. You will just attract a 
lot of spam and bounce a lot of spam for non-existent addresses to 
innocent victims. 
As a first thing stop sendmail on them or firewall port 25 on them. Then 
have your provider set up the correct records. Or use one of the many free 
or cheap DNS providers. Anyone of them is surely better than RoadRunner.
