Besides 6 or so BITNET hosts at Ohio State U., we have many small computer systems which are hooked up to OSU's campus network, and only have an Internet type address. How can I as the Listserv postmaster here, or by using the NAD's on OHSTVMA issue a global delete for a user on another system with an Internet type address? The Node administrator or postmaster for that system is undefined to Listserv.
