Hi there!
I just got to administer a NeXTstation. It used to be in a NetInfo domain, but
now it's an independently networked machine. 
When a send mail from it everything is OK. But when i try to send mail to it, 
the mail bounces saying that the service is not available. Here's a copy of a
bounced mail:
