If you are running a web hosting company and have to ask this you likely are not in a position to do what needs to be done.
Are you sure you mean that? Or are you just using cPanel from an inferior web host?
Mail-in-a-Box cannot do this without a major amount of aggravation, however I can indeed help you solve your problem with other tools. Even without the aggravation, you still have the issue of keeping the MiaB IP address clean.
