FIX: Errors occur when the AS2 Decoder decrypts an AS2 or EDI message that does not contain a MIME Content-Type header in BizTalk Server

SYMPTOMS
Consider the following scenario:
  • You have a computer that is running Microsoft BizTalk Server 2010, or Microsoft BizTalk Server 2006 R2 Service Pack 1 (SP1).
  • The AS2 Decoder decrypts an encrypted Applicability Statement 2 (AS2) or an encrypted Electronic Data Interchange (EDI) message.
  • The AS2 or EDI message does not have a MIME Content-Type header.
In this scenario, the AS2 Decoder cannot decrypt the message. Additionally, the following events are logged in the Application log:

Event 1
Event Type: Warning
Event Source: BizTalk Server 2006 EDI
Event Category: None
Event ID: 8132
Description:
An error was encountered when attempting to generate an AS2 status report. Error: Object reference not set to an instance of an object.

Event 2
Event Type: Error
Event Source: BizTalk Server 2006
Event Category: BizTalk Server 2006
Event ID: 5719
Description:
There was a failure executing the receive pipeline: "Microsoft.BizTalk.EdiInt.DefaultPipelines.AS2Receive, Microsoft.BizTalk.Edi.EdiIntPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "Pipeline " Receive Port: "<receive port>" URI: "<URI>" Reason: The Messaging Engine encountered an error while reading the message stream.

Event 3
Event Type: Error
Event Source: BizTalk Server 2006
Event Category: BizTalk Server 2006
Event ID: 5753
Description:
A message received by adapter "HTTP" on receive location "<receive location>" with URI "<URI>" is suspended.
Error details: There was a failure executing the receive pipeline: "Microsoft.BizTalk.EdiInt.DefaultPipelines.AS2Receive, Microsoft.BizTalk.Edi.EdiIntPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "Pipeline " Receive Port: "<receive port>" URI: "<URI>" Reason: The Messaging Engine encountered an error while reading the message stream.
CAUSE
This issue occurs because the AS2 Decoder does not treat messages that do not contain a MIME Content-Type header as plain text (US-ASCII).

Note According to a Request for Comments (RFC) memorandum that defines a standard for messages that do not contain MIME Content-Type headers, a default content-type should be assumed. The RFC states that any message that does not contain a MIME Content-Type header should be treated as a plain text (US-ASCII) message. This content-type is specifically defined as the following:
Content-type: text/plain; charset=us-ascii
