XCON: MTA Does Not Correctly Handle DDA Values With Equal Signs

ID: Q183064

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

If an X.400 address has Domain Defined Attribute (DDA) values set, and the DDA value string includes an equal sign (=), the message transfer agent (MTA) will not handle the DDA value correctly.

CAUSE

The MTA treats the equal sign as a field delimiter. If the DDA value is as follows:

XMROUTE: SN(u)U=X00Z(a)SN(u)L=KB00(a)MSR(a)D3000

then the MTA will truncate the DDA value to:

XMROUTE: SN(u)U

STATUS

Microsoft has confirmed this to be a problem in Exchange Server version 5.5. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.5.
