Contact Us Form

What I’d like is a contact us form, basicly like the comments but instead of it posting a comment, it would send a e-mail. Does anyone know how to solve that? I can genearlly use the template single page with comments but I’m not sure how to convert it so it sends a e-mail. I’d like to do it server based basicly, not so it comes up with your e-mail proggy.

Thanks!
