Garbled "From:" in a flash/php contact form

I have a contact flash/php form set up on my website. All works great except the the From: header in the email I receive contains strings related to the web host and a buch a html type code:

<mailto:<TEXTFORMAT LEFTMARGIN=“6” RIGHTMARGIN=“6”><P ALIGN=“LEFT”><FONT
FACE=“Verdana” SIZE=“12” COLOR="#FFFFFF" LETTERSPACING=“0”
KERNING=“0”>name@domain.com</FONT></P></TEXTFORMAT>>

The name of the sender and the message itself are fine.

Any ideas?
