If you do this, make sure you do not bounce from the scalix box or you will 
just add to the backscatter problem.
The best solution is to check the incoming mails for a valid destination, and 
drop those that are non-existent. If you blindly accept everything, you are 
now responsible to figure out how to pick out the typos from the forgeries, or 
never notify the people with the typos that their mail didn't go through. 
Because if you bounce all the bad recipients, you will get blacklisted. It is 
just a matter of time.
