HTML email that generates "!"s - any ideas?

Hi everyone, I am new to this list, so this is my first post. I am trying to sen dan HTML email, and so far I got everything running, except for one very odd problem. 1.) I am setting up all my variables within the .php Script. 2.) I generate my HTML email 3.) I am outputting the email to the browser and send it to myself --> Now here comes the problem: In the browseroutput the text looks like I want it to be. In the email however, there are several EXCLAMATION MARKS ("!") added to the code (and therefore the body). How can this happen?? Is there some trick I have missed? The exclamation marks are positioned within the email according to the amaount of characters I submit with the email. I have set up a simple page where you can view the .php file, the output and the email. http://www.gsdh.org/pleasehelp/index.html If anyone of you could spare the time, I would be really gratefull as I have to finish this but am stuck! :( Thans again, Philipp
