html email still sending as text/plain

Very strange..

I now uploaded the script to our server and made a test. All
data you get by POST were hardcoded in my testfile for saving time reasons
and I replaced my email adresses in th debug text before posting here ..

Everything worked fine. Here my debug text:

So your script seems to work. I didn't change anything from the codeblock I posted back
besides the POST data lines.
