[net.mail.headers] And, speaking of bad headers

Dave-Platt%LADC@CISL-SERVICE-MULTICS.ARPA (Dave Platt) (05/23/85)

my flying fingers put a bug into our mailer's configuration file;   it
decided that MIT-MC (which uses the ARPA node tables) is the same thing
as MIT-MULTICS (which knows about us of its own free will), so my
previous mailgram had a From: address which isn't usable by anybody
on the net.  Sorry, folks.
