I'm trying to determine whether there is anything I can do about the following error. The address has returned the "HOST UNKNOWN" message for at least two weeks. I tried TELNET NCC.UP.PT 25 and got a host unknown message as expected. Is there anything else I might do before deleting the subscriber from our list? Thanks in advance.
