Well, by default, the list:string field type does get a special Javascript widget, though the functionality could probably be improved. After you enter an item in the initial text box, hit enter, and a new box should appear below it, and so on. There is no way to remove a box once created.
Regardless of the widget, you can apply an email validator to each item in a list:string input using IS_LIST_OF(IS_EMAIL()). The only caveat is that validation errors will not automatically be displayed on the form, so you have to explicitly check for a validation error on that field and implement a custom error display.
