Aha. Then it's not a straightforward case of just adding the domain name to the same username, you need to transform the username too. Dovecot's userdb / authdb allows you to return a "user" field, which sets a new username for dovecot to use. Depending on what you use as your authentication backend, you may be able to do the transformation at that layer.
