XADM: Full Fidelity Not Maintained on Opaque-Signed Message


The information in this article applies to:
  • Microsoft Exchange Server, version 5.5


SYMPTOMS

When you send an opaque-signed message through a Microsoft Exchange Server computer, the full fidelity of the message may not be maintained.

Specifically, the loss of fidelity may include some missing Request For Comments (RFC) 822 specification headers, such as Disposition-Notification- To. This can be particularly relevant when using Electronic Data Interchange (EDI, or "e-commerce") applications, where the combination of opaque-signed messages and Disposition-Notification headers is relatively common.


CAUSE

This problem occurs when the Internet Message Access Protocol (IMAP) command "FETCH RFC822.SIZE" is called.


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 Microsoft Knowledge Base:

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



STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5.
