How do I change the "from" email address on the contact form module?

Hi,

My email is used as the admin email for a site we built and manage for a client, but the client does not want emails from the contact form to come from my email address. How do I change the “from” email address for a contact form? It seems like an important thing to be able to do.

I found this article here on the community site, and it has a link in the last post that is broken. I wonder if that old page had the solution.

Thanks
