Use a Form script that has some form of user response to complete the form; and is therefore secure from spammers. CoffeeCup is a good script that is not very expensive. Also, there are add-ons to Dreamweaver including Form2Mail, which creates a form and separate processing file.
Never put your email address on a form, and never have it in the code of the form page, otherwise spammers will abuse your form. That's the nice thing about the scripts I mention above - they have your email address and other form instructions in a totally separate file that the spammers can't see. And they require the user to do something like type in characters so the spammers can't mass-fill out your forms.
