Asking all the Canadian LISTSERV Postmasters to install CADOMAIN NAMES instead of DOMAIN NAMES won't be of much help, except of course for lists with peers in Canada only and DIST streams originating in Canada. Let's take a large DIST job with a lot of recipients in BITNET and NetNorth. If the job originates at a BITNET node (i.e., where the normal DOMAIN NAMES is being used), DIST will make *all* the path calculations at the originating node; this means that all addresses ending with .CA will be handled by the server at the .CA gateway, instead of being further exploded there.
