If you want to use dbm, just specify your map file as `dbm' --
alias_maps = dbm:/etc/postfix/aliases

You can create a script that can be executed once in a while that
extracts all users with UID >= 500 from your /etc/passwd file and
dumping them all to an alias file which Postfix can access. Just make
sure that you're the only one who can send to that alias as this
'feature' can be abused.
