This is very impressive! Best I have ever done was running Eudora on a workgroup server 60 in the late 90's to provide email for almost 1,000 users. I massaged that machine to run it flawlessly until I just couldn't expand the ram to keep up with the traffic - much less have enough storage or disk speed. I wound up converting that machine into a web server with web star and used it for that purpose into the early 2000's - without any trouble. Never occurred to me to try it on a machine still old. I do know of a company with over 150 workstations that still uses a IIci as a DNS and print server.
