Here's a naive question. Right now we are connected to the NJE network with UCBCMSA, a core site, upstream from us running Listserv NJE. Downstream from us, we are connected via VMNET or SNA to several NJE sites which also run Listserv NJE. UCBCMSA -- UCCVMA -- site 1 (core) (us) \ -- site 2 (and another via a separate link) We intend to leave Bitnet and license Listserv TCP/IP and LMail. The downstream sites may or may not leave Bitnet. All have LMail and VM TCP/IP, though one site is not running the VM SMTP. How do Listserv NJE and Listserv TCP/IP interact if I retain my direct RSCS links to the downstream sites? What can I do, if anything, to minimize the impact on the downstream sites? Do they need to connect to an NJE site upstream from me to minimize disruption? Thanks for any help. -- Richard Hintz [log in to unmask] University of California
