I would not check if the email is a duplicate or not. I agree there will be times/cases when two emails will be sent. But you would have a good explanation: "You sent two emails, therefore there are to postings in the application. Make sure not to email twice and you will not have a problem." :)
IMHO, this will simplify your task and avoid any "legitimate" complaints.
