>If I am subscribed to a list as LDW@USCMVSA, and USCMVSA's nodentry >contains :Internet.MVSA.USC.EDU, which path is my mail going to take? It will be routed to the closest LISTSERV to USCMVSA, and delivered to the mailer on that machine with a hostname of USCMVSA.BITNET; whatever happens from that point depends on the mailer, presently it will deliver via BITNET, if John changes this behaviour it may do something else. The :internet. tag is used in the other direction, ie if it sees MVSA.USC.EDU it will route the message via DISTRIBUTE to get as close to USCMVSA as possible, and finally deliver to the mail with the .USC.EDU address.
