I had this same misunderstanding few days ago (in my case using ldap, but it 
doesn't matter). The usage of variables makes sense when used in generic 
values (e.g. mail_location), but not when used in a per-user db, and so 
they're not expanded in that cases.

So: when adding a new entry in your passdb file, you should write actual 
values instead of variables. Usually it's really easy.
