BizTalk Server 2006 may be unable to decode the S/MIME information in the header of an incoming MIME message that was generated by BizTalk Server 2002

You can use Microsoft BizTalk Server 2006 R2 to decode an S/MIME message that is generated by BizTalk Server 2002. However, for an incoming MIME message that contains an S/MIME message, the decoder may be unable to decode the S/MIME information in the header. Therefore, the decoder may produce a zero byte document. For example, the encrypted messages from BizTalk Server may contain the 'application/x-pkcs' reference in the MIME header and in the signed part header.
