[net.mail.headers] "Unable to deliver after 0 days"

MRC@SU-SCORE.ARPA (Mark Crispin) (02/22/84)

     The particular strangeness about the message (that is, it is
unable to deliver after no time at all) is due to a fencepost error
in older versions of the TOPS-20 mailer.  It was fixed a while ago --
it now tries for at least a day before reporting an error -- but the
distribution of the new software is quite irregular.
