[suse-security] postfix

Hi, I just set up a postfix-mail system on a new gateway. Now I want to configure postfix in the following way: - mails from the inside-network should only be relayed to the outside-network, if the sender matches name@mydomain, otherwise the mail should be rejected - the gateway should not relay spam-mail etc. from the outside-network coming e.g. in the form name%domain@mydomain I'd be glad if anyone could help me how to configure postfix for this purposes. Thanks Michi mailto:michael.schorr@topmail.de
