Hello, > The change of beowulf.gsfc.nasa.gov to beowulf.org as the sender > address for the list has screwed things mightily here, because > beowulf.org does not resolve. It didn't resolve here, but now it does resolve again, maybe check the nameserver cache or the mail server cache. I had to restart sendmail to be able to receive the tulip mail again. Kind regards, Ulrik de Bie winmute
