Now, at some point if the customer decides to point their MX records to

aware of the change (and still has mapping in the internal "virtual"
maps. So at this point, if we send this customer an email at his domain,
the email will be delivered "internally" instead of being sent to his
NEW external MX host.
So how can we configure postfix so that it will "realize" that the mail
should be routed to the NEW MX host?
You can run some script periodically to check the MX of hosted
domains and send you an alert when one changes.
