The obvious alternative is NOT to use the Postfix UNIX-style local
delivery agent for non-UNIX users, but something else, perhaps
Andrew McNamara's virtual delivery agent.

If you must use Postfix local for non-UNIX users, consider creating
a dedicated aliases file with

    user: /path/to/mailbox

entries. If the aliases file is owned by UNIX user foo then the
mailboxes are written as UNIX user foo.

/etc/postfix/main.cf allows you to specify any number of alias maps.
Typically, the defaults are:

    alias_database = hash:/etc/aliases (used by newaliases)
    alias_maps = hash:/etc/aliases (used by postfix local)
