How can ANY mailer route to unknown sites? Where does "domain-based" >fit in? Routing is perhaps the wrong word here. Some mail transports require the end-point to be known. Using the bang routing notation, uucp only requires that each host on the path knows how to sent to the next site - beyond that is someone else's problem. That is, the "unknown site" can be unknown to everyone except the site immediately before it in the path. As to the active-rerouting debate that is going on here, the objection seems to be that often the site reached by parsing the path from the right side is not the same one that would be reached following left to right. Given the uucp map data that is being used for the re-routing, would it not be possible to determine (by common neighbors) if the new route is going to reach the same machine? Les Mikesell
