I've seen that, too, and assumed it was the null mail from. I wrote to their postmaster with a CC to the subscriber. The subscriber wrote back to me saying that at first they were trying to tell him that mx1-central.MIS.NET was -- get this -- NOT ONE OF THEIR SERVERS! Later, he said, "a more knowledgeable tech rep" acknowledged that it WAS their server and they weren't sure what was happening. I have never heard back from them. Another clueless ISP, I'd say. -- Peter C.S. Adams <[log in to unmask]> co-owner, PAGEMAKR mailing list <http://www.makingpages.org/> Help the environment!
