BINGO!
The email message contained the array and all its key => values.
I also had it just write the same thing to a local log file.

I suppose now i can get to any element of the array, like this..
$dwin_data['MySFfieldName']
and plug them into a database or something.

But of course i defer to you.. what do you do next?
And, what about the custom WSDL file (downloaded from my SF OutboundMsg setup)? That's not even used yet, right?

thanks..
