E-mailing scanned documents for patrons

When a patron requests that a scanned document be mailed, send the document to the patron only, not to the destination e-mail.  If you send it directly to the destination e-mail, then any returning responses from the recipient will come back to you instead of the patron.  Sending it to the patron also accomplishes the task of putting the scanned document back into their hands where they can control its distribution.
