I don't disagree. But my logic, based on Jim's post, is that the first step is to match the type of inquiry with the right email. I go by the rule of thumb that people don't read, so when he says that they have visual instructions what people should do ... I think the first step is to incorporate that into the form so users are providing them with the information needed to manage the communication. A pull down menu isn't going to stop any spammer, imo, but those are issues to resolve further once the needed information is being submitted within the form.
Jim, you're welcome, keep us posted!
