SYMPTOMS
========

An event similar to the following may be logged in the application event log:

  Event ID: 3150
  Source: MSExchangeMTA
  Type: Warning
  Category: X.400 Service
  Description:
  An internal MTA error occurred. Object 00000000 failed integrity verification.
  DB Attribute: 0. OM attribute: 0. Entity Name:
  /o=Site/ou=Server/cn=Configuration/cn=Connections/cn=Internet Mail Connector
  (SERVERNAME). [XAPI GATEWAY 30 1 130 (14).

The incoming message is lost and the sender does not receive a non-delivery
report (NDR).

CAUSE
=====

This issue can occur if the Internet Mail Service builds an invalid X.400
message. The message is invalid because the MTS Identifier (MTS-ID) is missing
the global domain identifier; only the local string identifier is present.

This can occur if the X.400 address of the administrator mailbox for the Internet
Mail Service is comprised of uppercase characters, for example:

  C=US; A=ADMD; P=PRMD; S=Administrator

The Internet Mail Service can only process the "c=," "a=," and "p=" if they are
lowercase characters.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
For additional information, please see the following article in the Microsoft
Knowledge Base:

  Q191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack


WORKAROUND
==========

To work around this issue, edit the E-mail Addresses raw property of the
administrator mailbox for the Internet Mail Service, and change the "C=," "A=,"
and "P=" in the X.400 address to "c=," "a=," and "p=."

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5. This problem was first corrected in Exchange Server 5.5 Service
Pack 4.
