What are you saying? Do you want to port-forward traffic coming in on
dom0's eth1 to different VMs?

    Dom0 (eth1)         DomU
  ---------           ----------
->  port 25     ->    VM1 port 25
->  port 80     ->    VM2 port 80
->  port 143    ->    VM3 port 143


Also, what distribution are you running Nicolas: Debian, Fedora, ...?
