I recommend that you do not reduce the 10 unless you plan on using internal emails from a business that has short email addresses, but that you do not raise the 10 so that you can avoid accidentally eliminating real contacts. Feel free to delete this message when you read it. It will not reduce the functionality of this contact form.
