     policyd is a policy server, which can be used in postfix, and can 
be used to acchieve quota limitations to help you solve this kind of 

     you should take a look in it: http://www.policyd.org/

     Making this limitation on dovecot, if possible, would limit the 
delivery only for your local users. And i'm sure your employees are also 
sending those powerpoint stuff to outside users as well. So, the right 
place to limit this is postfix, which handles all users, local and 
remote ones.
