You may use local_recipient_maps. On my home server, I have this in the 
postfix main.cf file:

mydestination = $myhostname, localhost
local_recipient_maps = hash:/etc/postfix/local_recipients, $alias_maps


/etc/postfix/local_recipients contains the list of the users allowed to 
get mail from the external, one by line: 

user1	OK
user2	OK
...


Fill it with the values needed, then run "postmap /etc/postfix/local_recipients", 
and reload/restart postfix.

Also, see http://www.postfix.org/LOCAL_RECIPIENT_README.html
