INTRODUCTION
============

The disk provided with this Application Note contains the External
Mail program (EXTERNAL.EXE), a replacement for the External Mail
program files that are included with version 3.2 of Microsoft Mail for
PC Networks. This update resolves the following problems:

 - NetBIOS notification does not work when the sender and receiver are
   on different postoffices and there are multiple External Mail
   programs running. The only time notification works is if the first
   External Mail program that was started up dispatches mail between
   the sender's and receiver's postoffices.

 - On Novell(R) networks, the RNETWORK.GLB file is not updated at 4:00
   A.M. on any drives that are dynamically attached.

 - In low memory conditions, the External Mail program deletes mail
   from the outgoing mail queue without returning that mail to the
   sender. There are error messages in the SESSION.LOG and SYSTEM.LOG,
   but the mail file is still deleted. In most cases, the sender is
   not notified that the mail was not delivered. With the updated
   External Mail program, the mail message is not deleted but remains
   in the outgoing queue, and the External Mail program still attempts
   to deliver the mail. Because there is not enough memory to return
   the message to the sender, there is no entry in the SYSTEM.LOG. The
   administrator can return the mail from the queue.

 - When the EXTERNAL.INI parameter MinKDiskFull is not included in the
   EXTERNAL.INI file, the default value of 0 is used. This causes the
   External Mail program to attempt to deliver mail to a postoffice
   that has no disk space. The default value for MinKDiskFull has now
   been changed from 0 to 100K.

 - When the External Mail program marks a dynamic drive as being full
   (no disk space), it is not checked again until the External Mail
   program is restarted. The External Mail program now checks dynamic
   drives that are full on every cycle, and changes their status if
   disk space becomes available.

 - Messages transferred asynchronously or through an X.25 connection
   do not get time stamped. Therefore, when you view the received
   message in Mail for Windows, the received date/time is actually the
   date/time it was composed, not the date/time it was received by
   External. The External Mail program now time stamps all messages.

 - The External Mail program sometimes hangs when CommType=X25EICON.
   The CommType setting can be specified in the .INI file or on the
   command line for External.

To update your MS-DOS EXTERNAL.EXE file
---------------------------------------

1. Insert the enclosed WA0891 disk in your floppy disk drive.

2. At the MS-DOS command prompt, type the following and press ENTER
   after each line

      copy <drive>:\external.exe <destination>

      copy <drive>:\*.ovl <destination>

   where <drive> is the floppy disk drive containing the WA0891 disk
   and <destination> is the drive and directory where your
   EXTERNAL.EXE and *.OVL files currently reside. For example, if the
   EXTERNAL.EXE and *.OVL files are located in the MAILEXE directory
   on drive C and the WA0891 Disk 1 is in drive A, type the following
   commands:

      copy a:\external.exe c:\mailexe

      copy a:\*.ovl c:\mailexe

   A message will be displayed after you run the first command
   stating: 1 file(s) copied. Then a message will be displayed after
   you run the second command stating: 3 file(s) copied. This
   indicates that your *.OVL files have been successfully replaced.

   NOTE:  The EXTERNAL.EXE and *.OVL files typically reside on the
   postoffice server in the Mail executables directory, as well as on
   the machine transferring messages to and from the database. Make
   sure you update all copies of the EXTERNAL.EXE and *.OVL files.
