This is a "hmmm" type question. Why does "whois" say there is no match for listserv.acsu.buffalo.edu or for the IP 128.205.7.35 ? nslookup says it is there and I never have any problems with the address from here (well, every once in a while, but not for a long time). Got a subscriber who can't do anything as her system keeps sending back to her errors, [log in to unmask] unknown host/domain. Her computer folk are at a loss as to why this happens. I have suggested to her that perhaps a "connection refused" (she always sends her stuff at 8 am her time which is 10 am Buffalo time) is being misinterpreted as unknown host/domain. I am obviously grasping at straws as I do not know. Any suggestions? Douglas
