SUMMARY
=======

After you enable the Message Journaling feature of Exchange Server version 5.5
Service Pack 1, if you send large messages to other users on your local Exchange
Server computer, you receive non-delivery reports (NDRs) similar to the
following:

   Your message did not reach some or all of the intended recipients.

   Subject: MSG Sent: 8/11/98 11:14 AM

   The following recipient(s) could not be reached:

   Exchange User on 8/11/98 11:16 AM Either the message size exceeds the maximum
   allowed for the recipient or transport, or you have exceeded the storage
   limit on your mailbox.

   MSEXCH:MSExchangeIS:Site:SERVER

MORE INFORMATION
================

This occurs when size limits are set on the Exchange Server message transfer
agent (MTA). Before you enable the Message Journaling feature, only messages
that you send to users on another Exchange Server computer go to the MTA, and
these are sent back if the size limit is exceeded. After you enable the Message
Journaling feature, messages that are sent to local users also go to the MTA
and, therefore, the size restriction is invoked.

Part of the Message Journaling feature, first introduced in Exchange Server 5.5
Service Pack 1, is to send all messages to the MTA for submission to the journal
recipient. This in turn causes the local messages to be subject to the MTA size
restriction. To verify if Message Journaling is enabled for messages destined
for recipients local to the server in question, check for the following registry
value:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem\No
   Local Delivery

NOTE: The No Local Delivery value is a DWORD type value.

If this value is non-zero, journaling is enabled for all messages submitted to
local recipients and is subject to any size restrictions that may be enabled for
the local MTA.

Additional query words: journal content too long mta
