XCON: SMTP Message ID May Be Incorrectly Truncated |
The information in this article applies to:
-
Microsoft Exchange Server, version 5.5
SYMPTOMS
When an Exchange Server computer generates a non-delivery report (NDR) for
an SMTP message, the message ID may be incorrectly truncated. For example,
if an NDR for a message came from the server yourserver.sub1.sub2.com, the
message ID should be as follows:
<uniqueNumber@yourserver.sub1.sub2.com>
However, Exchange Server generates the following malformed message ID:
<uniqueNumber@yourserver.sub1.sub>
CAUSE
The structure that contains the message ID has 128 bytes allocated for the
message ID. Because the message ID is created as Unicode, only 64
characters are allowed. The unique number portion of the message is 38
characters in length, which leaves room for only 22 additional characters.
If the fully qualified domain name exceeds 22 characters in length, it will
be truncated.
RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
