You should not save the master users credentials with the mail user
credentials. Instead you should use a dedicated userdb and passdb.

For further reference have a look at
http://wiki2.dovecot.org/Authentication/MasterUsers.

I don't undestand your question. You can either forward plaintext
credentials to your backend or authenticate on your proxy and go with
the proxys master user to your backend
