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, click the following article number to view the article in the Microsoft Knowledge Base:

191014 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 that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.
