Sorry, this is the support forum for the Now SMS/MMS Gateway product, so my priority is to answer support queries for our product. Unfortunately, I don't have time to reply to all non-product related questions.

I will say that it looks to me like a somewhat questionable header in text format. I seem to remember some toolkit that liked to generate a crazy header like this, but I can't remember which one.
