MX V5.1 ECO 11, 06-JUL-1999

*** This kit supersedes ECO 4

Change description:

   * Fix a problem in the SMTP address parser that would cause
     addresses to be quoted unnecessarily.

Other changes (from ECO 4):

   * Fix a problem in the LOCAL_USER routine that would cause
     the Local delivery agent to either ignore deliveries to
     DECnet addresses, or exit with an access violation error.

   * Add support for a logical name to disable the
     sending of a "message delayed" DSN on the first
     failed attempt to send a message.

     $ DEFINE/SYSTEM/EXEC MX_DSN_DISABLE_INITIAL_DELAY_NOTIFICATIONS TRUE

     The value of the logical name is unimportant; the
     extension will be ignored if the logical name exists.

     By defining this logical name, DELAY notifications will only be
     sent if the message remains in the queue for re-try for over 12
     hours (or whatever interval is defined by MX_DSN_NOTIFICATION_INTERVAL).

Installation:

    1. Copy the appropriate image (VAX or Alpha) to MX_EXE:

          $ COPY MX_SHR.{AXP|VAX}_EXE MX_EXE:*.EXE

    2. Shutdown and restart all of MX:

    	  $ MCR MX_EXE:MCP SHUTDOWN
          $ @SYS$STARTUP:MX_STARTUP

* If you have a mixed VMScluster with both VAX and Alpha systems,
  you will need both images - one for each architecture.

* If you run MX on multiple nodes in your cluster, you should execute these
  steps on each node in your cluster.
