If you return a host setting, Dovecot handles it as login referral: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Host

So you need to return proxy=null and host=null.

If that doesn't seem to help, set auth_debug=yes and verify from the logs that neither of them are returned by auth process.
