Postfix mailer being rejected as relay spam.



I have a linux system which is on a DSL line. The system is being used as a web server and is running a half-dozen ip's assigned to virtual hosts. The problem is that outgoing mail is being rejected as spam because the recipient can't resolve the FQDN of the server. In particular, any mail sent by the server is seen as coming from x.x.128.238 which is the gateway address of the DSL interface to the server. There is no domain assigned to this gateway address which causes the mail to fail with "RELAYING DENIED -- Ip name lookup failed for x.x.128.238".

Is there a way to get Postfix to use one of the virtual host ip's to fix this problem?
