Is there a way to limit the submissions based on the email address when using the Webform module in Drupal? Right now, there is a setting to limit using the ip address & cookies but I only want to limit using the email address. Anyone has any ideas?

Edit the email field in the webform and check both the "mandatory" and "unique" options. That way, it will not except more than 1 submission with the same email address.
