If you use fully qualified domain names whenever there is ambiguity, then your own mail will not be bounced. If (random, internal) hosts put their fully qualified domain names in Path: headers, then this path would look like "bionet!oracle!decwrl!sgi!oni.sgi.com!apple.oni.sgi.com!user" et voila, no ambiguity, no bounced. And besides, if someone actually is posting news from this apple machine internal to sgi, that news will never make it to the "real" apple, if it puts "apple!" into the Path header and it's in the maps. Posting from "urania" but you'd never know it, --Ed Edward Vielmetti, U of Michigan math dept
