By default, Postfix has smtpd_sasl_type = cyrus Why don't you set smtpd_sasl_type = dovecot and follow SASL_README instructions to configure Postfix as if it will use Dovecot? The only interaction betweeen Postfix and Dovecot is to get a list of authentication mechanisms, which Postfix wlll never use. I think that is a small sacrifice to make if you want to use Postfix in a manner that has never been tried before. Wietse
