  11.     1.01    /usr/src/sendmail.8.6.12/cf/cf/obj/elijah.smtp.cf section
  12.         lacked the following items:
  13.  
  14.         < OcTrue
  15.         > OcFalse
  16.  
  17.         Consequences:    None, if You updated the .mc and .m4 files
  18.         as instructed, and performed 'make' on them. Big if You
  19.         edited /etc/sendmail.cf directly --- omitting this change
  20.         would make the patch NOT WORK. Remote mail would be
  21.         delivered same as local, immediately.

  26. If all the below instructions is followed, it even works during boot!
  27. REMOTE MAIL will not be delivered from the mail queue unless a user
  28. executes sendmail -q.

  30. At the end of the document is some suggested edits to
  31. /var/X11R6/lib/fvwm/system.fvwmrc to give some menu support for this
  32. for the benifit of Linux hackers and others! Some of those edits assume

  51. Create system mail queue and hideaway for system mail queue files
  52. to be used while starting the sendmail daemon during system boot:
  53.  
  54. mkdir -p /var/spool/mqueue /var/spool/mqueue.hide
  55. chmod 0700 /var/spool/mqueue /var/spool/mqueue.hide

  59. Start the sendmail daemon section of /etc/rc.d/rc.M heavily re-programmed:
  60.  
  61. The below section starts the sendmail daemon so that it won't process
  62. "expensive" mail the first time around. And so "delivery runs" are NOT
  63. performed every 15 minutes. The -os flag makes ALL mail queued (that
  64. doesn't mean it can't be delivered immediately all the same).
  65.  
  66. Delivery happens when any user runs "sendmail -q".
  67.  
  68. # Start the sendmail daemon:
  69. if [ -x /usr/sbin/sendmail ]; then
  70.   # If the queue isn't empty, stash away the queued items in mqueue.hide...
  71.   mqquery=`/usr/sbin/sendmail -bp`    # mqquery=`/usr/bin/mailq`
  72.   if [ ! "${mqquery}" = "Mail queue is empty" ]; then
  73.     mv /var/spool/mqueue/* /var/spool/mqueue.hide
  74.   fi
  75.   echo "Starting sendmail daemon (/usr/sbin/sendmail -bd -os -q)..."
  76.   echo "[Special note: As configured on this system, REMOTE MAIL is queued only!!!]..."
  77.   /usr/sbin/sendmail -bd -os -q        # "15m" removed from off the "-q" flag!
  78.   if [ ! "${mqquery}" = "Mail queue is empty" ]; then
  79.     echo "[/var/spool/mqueue wasn't empty, now being copied back from mqueue.hide!!!]..."
  80.     sleep 2; mv /var/spool/mqueue.hide/* /var/spool/mqueue
  81.   fi
  82. fi
  83. #
  84. # There is an alternative solution, but this approach queues *only* ALL MAIL,
  85. # LOCAL TOO. It goes like this, and doesn't need any /var/spool/mqueue.hide,
  86. # nor all the reconfiguration of sendmail.cf that will follow further below:

  88. # # Start the sendmail daemon:
