Andrew's system "virtue" was the VMS site I referred to in my previous
posting <1990Feb14.010521.23324@kaukau.comp.vuw.ac.nz>, and it does appear
that the duplicates we get are caused by the message-id's used in the IHAVE
exchange being lowercased (ie. all the duplicates we received had
Message-ID's with uppercase letters in the local part of the ID).  So does
ANU-News do this? If so why?

Message ID's are supposed to be governed by rfc822.  The domain part after
the @ is case insensitive but the local part IS case sensitive (with a few
special case exceptions).
