MX V5.1 ECO 14, 31-OCT-1999

[includes changes to SMTP server for TCP/IP from ECO 8]

Change description:

   * Added a SITE callout for the SMTP server to provide
     additional "inside network" checks beyond those configured
     through the DEFINE INSIDE_NETWORK command in MCP.

     The file LOCAL_NET_CHECK.C in this kit provides a sample
     implementation of this callout, with instructions on 
     building and installing the appropriate shareable image.

Change description from ECO 8:

   * Fix the SMTP servers' command parser so it allows for
     relaxed address parsing (for DECnet addresses without
     quotation marks and usernames without domain names)
     on extended SMTP commands that include parameters.

Installation:

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

          $ COPY SMTP_SERVER.{AXP|VAX}_EXE MX_EXE:*.EXE    (for TCP/IP)

    2. Restart the SMTP server over TCP/IP:

          $ MCP SHUTDOWN SMTP_SERVER
          $ @SYS$STARTUP:MX_STARTUP SMTP_SERVER

       Repeat the startup invocation on each node that runs the
       SMTP server.

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