I have installed and new spam filter between the firewall and mail server. I am now using port forwarding. The outgoing traffic for mail is being stamped with my Pix address instead of the mail address. Some of the mail is being rejected becasue the pix outside address has no rDNS. Is there a way to make the out going mail use the mail server external address instead if the PIX external address.
