The postfix feature for this is described in http://www.postfix.org/RESTRICTION_CLASS_README.html The restriction class method get rather awkward if you define more than a dozen or so classes. In that case you would need to use an external policy service. http://www.postfix.org/SMTPD_POLICY_README.html Some pre-made policy services are listed here, or you can use one of these as a basis for something of your own http://www.postfix.org/addon.html#policy -- Noel Jones
