I am not sure that there is a topology -- may be a spider web. The UUCP network is a collection of hosts who are connected to one or more neighbors via dialup telephone links. USENET is a news distribution system that uses several types of connections to forward news. Problems occur because a USENET news path is used a mail address when the article is forwarded to INFO-CPM as mail. I know that some UUCP hosts relay a lot of mail, and that a reasonably good mailing path can be constructed from the Usenet string *if* you know who talks to whom. I don't. A UUCP mail address contructed from a USENET path may work, but is often not reasonable or cheap. Again, do not assume that USENET news distribution path is a UUCP mail address. Some USENET links are not mail links. Some sites do not even use UUCP to transfer news or mail. Most USENET paths show that the news article took the scenic route, not the freeway to get where it was going. Bill Wells wcwells@Berkeley.ARPA ucbvax!wcwells P.S. If you would like to discuss UUCP mail addresses/USENET news paths further, I suggest moving this discussion to the msg-group mailing list.
