This type of mail is produced when you have a VAX which is NOT on
BITNET using VMS Mail and DECNet to send mail thru a VAX running
Jnet which is on Bitnet.  Here is an example of what such mail
looks like when received on my VM system:
 
---------------------------------------------------
Date:     Mon, 23-FEB-1987 14:02 PDT
Original_From:  MAC::JXH(John Halperin)
Comments: This is gatewayed mail.  Warning:  Mail may not
          necessarily be returnable through this path.
From:     General Delivery <POSTMASTER@SLACASP>
Subject:  test2
To:       jxh@slacvm
Original_To:  ASP::JNET%"jxh@slacvm"
 
----------------------------------------------------
 
In the above example, I sent mail from our 'MAC' VAX over DECNet
to Bitnode SLACASP which gatewayed it to SLACVM.  Note the Original_To:
and Original_From: lines in the header.  These are your only clues to
the original sender.  Unfortunately, they seem to be getting removed
by LISTSERV.  I leave it to better minds than mine to decide who is
to blame.
