The answer is that point (b) is just historical. The code used to get rid of domain addresses as soon as possible, substituting a valid gateway nodeid instead, and there was no support for domain addresses in the service areas. It just happened that the gateway node was used for this purpose, and in practice all domain addresses were in the US and routed via a US gateway, so it worked just fine :-) I have changed the code to allow you to do what you want, ie the domain nodeid itself is used for the service area calculation, rather than the gateway. Since this is a bug rather than new development, the change is available to EARN and I have sent you a copy. However, I stand by my previous statement that I will not ship any fix shipment to EARN sites, so that nobody can pretend that I have purposefully introduced bugs in the code just before handing the support to EARN. The fix is available from me on request; just before I stop supporting LISTSERV for EARN sites, I will make a shipment containing all the EARN fixes since FIX15O1 (at present that's just the one I just made) and will make it available from a service machine, with a disclaimer recommending NOT to install it unless the local staff can commit to fix any bug that may have been introduced there, as I would no longer support them, FIX15O1 has no known major bug, and it is not yet known when nor how EARN is going to provide support for LISTSERV.
