Have you read all the comments in /etc/postfix/main.cf ?? I just took a quick read and there is a lot of info there for dealing with relaying....
I have, but I can certainly go through it again.
As far as I can understand your problem is in the following areas. http://netmirror.org/mirror/postfix.org/documentation.html mynetworks_style (default: subnet) The method to generate the default value for the mynetworks parameter. This is the list of trusted networks for relay access control etc. * Specify "mynetworks_style = host" when Postfix should "trust" only the local machine. * Specify "mynetworks_style = subnet" when Postfix should "trust" SMTP clients in the same IP subnetworks as the local machine. On Linux, this works correctly only with interfaces specified with the "ifconfig" command. * Specify "mynetworks_style = class" when Postfix should "trust" SMTP clients in the same IP class A/B/C networks as the local machine. Don't do this with a dialup site - it would cause Postfix to "trust" your entire provider's network. Instead, specify an explicit mynetworks list by hand, as described with the mynetworks configuration parameter. proxy_interfaces (default: empty) The network interface addresses that this mail system receives mail on by way of a proxy or network address translation unit. This feature is available in Postfix 2.0 and later. You must specify your "outside" proxy/NAT addresses when your system is a backup MX host for other domains, otherwise mail delivery loops will happen when the primary MX host is down. Example: proxy_interfaces = 1.2.3.4 Network design however I would consider a rethinking as this is what causes most of the problems right now.
