It is best used that way, especially if per-user lookups involve LDAP,
MySQL or similar. A more complex, but more performant solution is to
rewrite each type of user to a suitable domain that is routed to the
right place. Then, if absolutely necessary use smtp_generic_maps to
rewrite back to the original address during SMTP delivery, but better
to have each destination accept non-public internal "route" addresses.
