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??
