If you remove the auth_bind_userdn, it does a lookup using pass_filter
and pass_attrs.

And when such lookup is done, it reads the domain, and changes the
username to user at postalAddress and %d expands to postalAddress then.

Yes, but even though you see it in logs, it's completely ignored by
everything.. Unless you use latest v2.0 hg.

There's no simple way to currently use random userdb fields in
mail_location. Maybe some day.
