Steve,

I couldn't agree with you more.  But when I tried to send a reply to you,
I looked at the the header I received:

My mailer (and I doubt any mailer), can discern who 'rand-unix' is.  It could
be a node in csnet, it could be a node in mailnet but it happens to be a
node in Arpanet.  I have found very often that nodenames in Bitnet are the
same as nodenames in Arpanet and quite often they are not on the same host.
A fully qualified return address to you is 'greep@rand-unix.arpa'.  I'm
sure mail handlers in other domains other than Arpanet have the same problem
and usually the user either hand massages the 'To:' field or the mail gets
bounced because rand-unix is undefined.

People who live in accelerators shouldn't throw electrons!
