I am using formmail and it's great! The only thing I'm noticing is that when I use the:

<input type="hidden" name="filter" value="null" />
<input type="hidden" name="filter_options" value="Attach=testform.html" />

in order to receive my results as an attachment, it's not following the template formatting I'm setting regardless if it's HTML or PLAIN text. The template shows up fine in the actual email body...just not the HTML attachment file. I'm creating forms for a medical office and it's illegal for them to receive patient info in the email body which is why it's is so important that the HTML attachment works properly. It's basically showing up in the browser window as one gigantic run on sentence.

Any suggestions to make this more printer/reader friendly?

Thanks for your help!
