nvoice Went to Incorrect Email Address

The key to this problem is the name of the PDF file.  The email was not sent by the Email Delivery program but instead was sent through the Invoice Reprint program and the User either chose the wrong Invoice or entered the wrong email address. Invoices sent through Email Bill Delivery are saved as invoice#.pdf whereas Invoices sent through the Reprint program are saved as Single Invoice Reprinting.pdf.
