needless to speculate until there is no exact detailed description how spamfirewall in this case Portimail works, this is the postfix mail list, recommands how Portimail should be connected to i.e postfix, should provided by Portimail not vice versa after all i couldn found somthing usefull at Portimail by websearch i found fortimail http://www.fortinet.com/products/fortimail/ as it looks like a commercial product, ask their support for fortigate ( the firewall solution ) , there is nat mode, and transparent mode, antispam,antivirus is optional, speculation you need to know what mode you re running to goal best postfix config at minimum, there is also a product itself called fortimail ( which seems to be a full working mail solution ,no need then ,for postfix ) > -- Best Regards MfG Robert Schetterer
