How about putting in smtprelay.tab all non-routable private subnets per
RFC or some kind of wildcard or special entry that matches the subnets
of all installed network cards in the xmail server?

For example, case 1:
smtprelay.tab
10.0.0.0/8
169.254.0.0/16 
172.16.0.0/12 
192.168.0.0/16 

or case 2:
smtprelay.tab
localsubnetsonly

hmm just found in http://www.faqs.org/rfcs/rfc3330.html that case 2
maybe should be 0.0.0.0/8 meaning "Addresses in this block refer to
source hosts on "this" network."
