MX V5.1 ECO 08, 01-MAY-1999

Change description:

   * 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)
          $ COPY DNSMTP_SERVER.{AXP|VAX}_EXE MX_EXE:*.EXE  (for DECnet)
          $ COPY XSMTP_SERVER.{AXP|VAX}_EXE MX_EXE:*.EXE   (for X.25)

    2. If using the SMTP server over TCP/IP, restart it:

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

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

* The SMTP servers for DECnet and X.25 require no additional
   commands after copying them to MX_EXE.

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