Restarting Mailscanner instead of sendmail

We have virtualmin pro installed and when we add a new domain for mail hosting we need virtualmin to restart mailscanner rather than just sendmail. Where can I make this change in the virtualmin. I’m using it on a CentOS 5 server. Thanks.

Ok, maybe I can simplify this a bit. How does virtualmin know how to restart sendmail? If I know that I can point it at the MailScanner init.d script instead and that should fix my issue.
