SYMPTOMS

Consider the following scenario:

You create a receive location to receive and to process MIME and S/MIME messages in Microsoft BizTalk Server 2006 R2 or in Microsoft BizTalk Server 2009.
You use a pipeline that includes the MIME/SMIME Decoder pipeline component in the receive location.
You receive a signed or encrypted MIME or S/MIME message in BizTalk Server 2006 R2 or in BizTalk Server 2009.

In this scenario, you may experience one of the following problems.

Problem 1

The message is suspended. Additionally, an error message that resembles the following is logged in the Application log:

Event Type: Error
Event Source: BizTalk Server 2006
Event Category: BizTalk Server 2006
Event ID: 5753
Description: A message received by adapter "<Adapter Name>" on receive location "<Receive Location Name>" with URI "<URI>" is suspended.
Error details: There was a failure executing the receive pipeline: "<Pipeline name>, <Pipeline assembly name>, Version=1.0.0.0, Culture=neutral, PublicKeyToken=<Token>" Source: "MIME/SMIME decoder"
Receive Port: "<Receive Port Name>" URI: "<URI>" Reason: There was an authentication failure. "Failed to decode the S/MIME message. The S/MIME message may not be valid."

Problem 2

The message is received by BizTalk Server 2006 R2. However, the MIME boundary is included as part of the message. Therefore, the message is incorrect.

Note These problems also occur when you use the POP3 adapter in the receive location.
Note:If you use BizTalk Server 2009, the Event Source and Event Category in above events are “BizTalk Server 2009”.
