Since we have no means to know that the MX records were modified, then we can't "remove" those virtual mapping rules from our database.

 $ dig mx example.com | grep -A1 "ANSWER SECTION" | grep MX

You have a problem with your users chaning MX without notifying you. THAT is your problem, not postfix.
