Thanks for the reply.
The problem is not the partner.
It is that webMethods is returning an invalid MDN response. The partner is able to accept any of the standard AS2 responses.
Part of the AS2 security provides for signing an MDN response that is supposed to guarantee nonrepudiation.
To provide the MDN report along with the signature requires using a multipart response.
Even if the security is omitted, the MDN received by the partner is not valid. Somehow the correct response is being “intercepted” and wrapped in a text/html document as if it is a report for internal audit purposes. How do I identify the module that is wrapping the actual MDN?
