The blurb below from this article, http://postfixmail.com/blog/index.php/postfix-relay-control/, leads me to believe it might be helpful in understanding and/or fixing your problem. "The mynetworks parameter allows you to set individual IP Addresses or subnets. When this parameter is used the mynetworks_style parameter is ignored. In the example below an internal private network is included as well as a public subnet. The example also includes a single IP Address. This gives you flexibility in configuring the options. mynetworks=192.168.5.0/24 12.32.34.32 216.168.0.1/24 > The only problem in the above example is that it requires that users have > static Ip Addresses. If they have dynamic IP Addresses then Postfix must be > configured fro SMTP authentication." _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
