trouble in contacting another host

[Paul Anderson]

I have been trying to get hold of  jwp at uwmacc.UUCP  to give him some
information he requested on info-unix message 3386, 13 sept 1985.
All I keep getting is '550 jwp at uwmacc.UUCP... Host unknown' errors.
I also tried it without the '.UUCP'.  Is this the correct address
(uwmacc.UUCP is as it appeared in message 3386)?  Is the host down?
Requesting information and assistance.
