[net.mail] How can I once again mail into arpanet from usenet?

olmstead (02/08/83)

I useta could send mail to friends at Xerox via:
"...sytek!menlo70!ucbvax!person@Parc-Maxc";
this worked until about January 1, when the arpa world went kablooey.
Now I get returned mail which appears to show Berkeley getting into one of
the mail servers at Xerox, and the Xerox server rejecting the message because
"I don't know that domain..."

Can anybody tell me whether it's still possible to send into the arpanet?
A friend says that arpa policy is to disallow inbound traffic, and that maybe
they're finally starting to enforce it.
If it is possible, can you tell me how?
