This is a Xen box (virtualization) all servers are running on domU
(guest).  I have only one external IP.  The local IPs of the host and
guest are as follows;

Host 192.168.0.110
guest_1 192.168.0.201 (xen01.satimis.com)
guest_2 192.168.0.202 (xen02.satimis.com)


All ports 25,80,143,443,etc.are now forwarded to 192.168.0.201
(guest_1).  That is the network setup here.


For Unix mailbox there is no problem on send and receive mails.
