Yes, It's true, I have to explain the scenario: Xmail is fully operative in our lan, it manages all messages from an internal (private) domain which is working perfectly. Since Xmail is using an invalid Ip address for the InterNet, I mapped = port 1300 from a virtual ip to port 25 of xmail server address. I configured = a client in internet to use the firewall's port 1300 to send mail and it = works ok. I need to put an authentication mechanism to avoid the use of the = smtp service to unknown external hosts and permit the use of this service = without authentication inside the lan.
