Changing Sender Name and Sender Email when emailing from website

Hi,

I've just installed HTML Email Templates because I was looking for a way to change who the email comes from on my website.

When someone receives the email, it says Wordpress as the sender, with wordpress@mysite.com as the sender address.

Can I change this? Or was this the wrong plugin to do so?

I like the idea of modifying the email format that this plugin accomplishes, but when it comes down to it, the most important thing I need to have happen is to change the sender name and sender email address.

Thanks for any thoughts on this.
