My last message to the kerberos mailing list got a bounceback--the
copy for Steve Miller at DEC came back with the message "host unknown".
I thought it was a problem inside decwrl, so I forwarded it to their
postmaster, who replied. . .

I checked our local domain name server (strawberry) and it answered
with three (!) different addresses for decwrl.arpa, a time to live of
about one day, and a note that the primary name is decwrl.dec.com.
Then I checked the nic domain name server, and it answered,
presumably authoritatively, that the name decwrl.arpa is not known.
1. Jeff: how does strawberry know things that sri-nic doesn't? Does
it have a pirate (out of date) copy of the .arpa authoritative data
base? If so, it looks like being out of date leads to an obscure
kind of bug--our outgoing SMTP can get their address but their
incoming SMTP claims it isn't the place we are trying to talk to.
2. Steve: could you please fix your forwarding address to use the
new domain name?
