I assume you have read this:

smtpd_sasl_auth_enable (default: no)

    Enable SASL authentication in the Postfix SMTP server. By default,
    the Postfix SMTP server does not use authentication.

    If a remote SMTP client is authenticated, the
    permit_sasl_authenticated access restriction can be used to permit
    relay access, like this:

        # With Postfix 2.10 and later, the mail relay policy is
        # preferably specified under smtpd_relay_restrictions.
        smtpd_relay_restrictions =
            permit_mynetworks, permit_sasl_authenticated, ...

        # With Postfix before 2.10, the relay policy can be
        # specified only under smtpd_recipient_restrictions.
        smtpd_recipient_restrictions =
            permit_mynetworks, permit_sasl_authenticated, ...

    To reject all SMTP connections from unauthenticated clients,
    specify "smtpd_delay_reject = yes" (which is the default) and use:

        smtpd_client_restrictions = permit_sasl_authenticated, reject

    See the SASL_README file for SASL configuration and operation
    details.

I don't know if that will help you or not. I still think that this is a
Postfix misconfiguration problem. Did Victor comment on it in the
Postfix forum?
