1) Use passwd-file, not passwd

2) userdb has no effect on proxying, it must be passdb.

If you really want to keep using PAM, you need to use Dovecot v2.2 with an additional passdb configuring the proxying for the users. http://wiki2.dovecot.org/PasswordDatabase#Passdb_settings explains more. It can’t be done with v2.1.
