Sander Roosendaal 74e924a3c1 send email to sender of unrecognized file 
The email processing sends a notification message to the person who
sent a unrecognized file to the workouts@rowsandall.com email address.
This way, people will know that their email has worked and perhaps
stop sending 99 or more emails with the same unsupported file.
