When I send a "QUERY IBM7171" command to my local, backbone, LISTSERV, I get: !------- ! From: Revised List Processor (1.7b) <[log in to unmask]> ! ! > query ibm7171 ! There are several "IBM7171" lists on the LISTSERV ! network. Please select one from the following list ! and resend your request to the appropriate server. ! IBM7171@IRLEARN Protocol Converter List ! IBM7171@UIUCVMD Log files only !------- Notice that IBM7171 at TCSVM is not mentioned. Why? Of course, if I send the same QUERY command to LISTSERV@TCSVM, I get the "correct" answer: !------- ! From: Revised List Processor (1.7b) <[log in to unmask]> ! ! > QUERY IBM7171 ! You are not signed up to list IBM7171. !------- Explanation, please, and thanks for your help.
