Hi Bo Nesbit,
Why not just use the out-of-box Email data cnnector? Tools->Data Connections->Add->E-mail->... ? That's a lot easier and you don't have to maintain code.
But, if you really want code, you can definitely do the same thing. There are lots of posts in this forum and information in the 2003 SDK (see InfoPath Resources link on left) that shows how to access the XML DOM from code.
May your path be garden variety,
