I have set up my domain to use google apps for its mail server. I have set up the appropriate MX entries in DNS. Any mail sent from the server to outside mail works fine. The problem is when I am sending mail to users on my domain. For example mail to "email@example.com" will go to my local mailbox for user "me", instead of checking the MX record for example.com and going to gmail.
I have searched google for hours and found people with this same problem, I haven't found any solutions yet though.
EDIT: For the record, I have DontProbeInterfaces set to true and I don't have the my domain in Class w
