So long as you have MTA = sendmail in MailScanner.conf, it will pick up 
the right one (if you are on Linux) automatically. Make sure you have 
done a
chkconfig sendmail off
chkconfig postfix off
as you want to leave MailScanner to start all the required 
postfix/sendmail processes for you.

On my own MX's I have just had to
rm /etc/init.d/sendmail
as while I was away one of my guys accidentally started sendmail with a 
service sendmail start which made it bypass MailScanner altogether. By 
deleting that file they have no way of "nicely" starting sendmail on its 
own at all, so that they are forced to use "service MailScanner start" 
to get it going properly.
