That is really weird...my first post on this subject disappeared into thin air. Anyway, I had a node ESCAPE.COM which had a user on my list. This morning, mail started bouncing for the user saying "unknown user". I let it go and by the afternoon the bounces started saying "node does not exist" or something like that. When I sent a test message it bounced, saying my system has no knowledge of ESCAPE.COM (even though it existed only yesterday). Any clues?? -nate
