Hi all,

I think this is related somehow to the bugbear virus. Note that the IP
63.123.249.67 might belong to a DSL/Cable company, and it is probably an
user's IP trying to disseminate the virus. When they try to connect to
the MTA, the MTA refuses to RELAY for this IP and therefore you have a
NOQUEUE error.
If only we had a list o networks that belong to DSL users.......!

Good luck with that!
