I have a subscriber to my list, Grunge-L (Ubvm.cc.buffalo.edu) who is subscribed from Net4LS.boat.bt.com Every day or two, I begin to get error messages claiming that the site is unknown. Yet, this subscriber posts to the list, etc. We're now on 1.8b (I think...) so, he gets automatically deleted too. He posts to our list frequently, and is a "good" subscriber, in that he does not violate etiquette, etc... I did a nslookup, and it returned no Address (A) records for the site. Any ideas? Thanks, as always, in advance. Blaine Owner Grunge-l, Autos-L Co-Owner Mud-L
