Why don't you then just create both domains in kolab, create two 
accounts (one for the private guy, and one for the business man) and 
read the two accounts with the same software (I'm doing it on my own 
server, right now). The alias system if mainly meant for receiving mails 
from two different accounts. It has nothing to do with outgoing mail.
