I haven't set it up myself, but MailScanner supports postfix, so I don't 
see why it wouldn't work.  After looking at the MailScanner Installation 
Guide for Postfix, my only question is whether the version of postfix 
for Kolab is setup to use a chroot jail?  Even though the MailScanner 
instructions want it, I wonder if we can/should get away with not having 
a chroot jail setup for postfix?

Everything else seems pretty straight forward.  You will probably end up 
needing to modify the startup files/templates for postfix so it does not 
blow away your configuration changes and to support launching two 
instances of postfix (an incoming and outgoing instance).

I did not find any hits on the website or in the openpkg-users mailing 
list for packages for MailScanner available for OpenPKG.
