Thank you, that was it.
The wwipstuff.cContentType should be "text/plain", not just "text" as it was. Interesting enough, I am using wwipstuff for about 5 years in many applications and for various customers using different email systems. And I always used just "text", and have never met this situation.
Thanks again
