Actually, wb2yxy has some suggestions which led me to look at the
ampr.org.rev file on ucsd. This has the same format as the db files
and I would think that renaming it to db.44 (and referencing it in
named.conf should work, although I haven't tried it.
Pine has a configuration option to relay all mail to a specific host,
which bypasses the MTA altogether. I did use this at one time to
handle amprnet traffic, but it was also a kludge, of course. This also
required me to use separate login names for amprnet and internet mail.
