Thanks Greg. I suspect you are right in so much as PMDF is mangling the message somehow. I'm not sure what the latest and greatest method of integrating Exchange and PMDF is...especially since after that Q was written, PMDF was dropped by Innosoft and picked up by Process Software (the same guys that support MultiNet, another pain in my side but we won't get into that now)

First, as identified in the following Q-article, Innosoft does not appear to even support this configuration. http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q185107&; Innosoft recommends connecting to Exchange via X.400, not SMTP and SMTP connectivity to Exchange is not recommended or supported (unless something has changed since this Q-article.) I would be willing to bet that the issue that you are experiencing is very similar in nature to the issues in the Q-article. It likely is some issue with the PDMF client or gateway not properly formatting the MIME message. Let me know if any of this is helpful or if you need some additional information. The simple fact that Innosoft does not support your configuration is a pretty damning evidence to the fact that PMDF is at fault. > Here's the story.
