Regardless if you're going to quote the user's name or not, you're still going to need to use a scripting language such as PHP or ASP. You have to instantiate an email object (of your choice), provide the necessary parameters (To address, From address, message, etc.), then use the object's "Send" function. Now the question you must ask yourself is this... Does my server support any server side scripting? If so, which ones?
Edit: Of course, you could also look into davesw's suggestion!
