# outmail - send all files in /var/spool/out.going
# by Robert R Schneck
#
# This program sends all the messages in directory /var/spool/out.going
# using ssmtp -t.  
#
# It leaves a copy of each in the file /var/spool/gone.out
#
# It exits 0 if all messages were sent, 1 if any failed,
# and 2 if you tried to run this script twice simutaneously.
# The locking mechanism to check for that is completely ad hoc;
# trust it at your own risk.
#
# I like to have the mailhub set the Message-ID: header; you
# can uncomment the line with "killmsgid" below (and comment
# the following line) in order to strip any Message-ID: headers
# from the outgoing mail.  Make sure the killmsgid script is
# somewhere in your PATH.

#    but WITHOUT ANY WARRANTY; without even the implied warranty of
