All, A friend of mine asked that I post a note here letting everyone know about a problem at his school, the South Dakota School of Mines and Technology. He doesn't know what the problem is, but the result is bounced mail from the site with "user unknown" identified as the error. I tried sending mail directly to him last night and got the same result. He's been having his students join lists as part of their coursework and many have been booted because listowners (naturally) think the IDs don't exist. He assures me that the IDs *do* exist and hopes everyone will be as tolerant as possible until the problem is corrected. --Eric Crump
