7.  In this case, the Watchguard firewall was the culprit in rejecting the attachments.  By default Watchguard sets attachment restrictions to 10mb.

8.  To change the Watchguard Firewall settings.  Log in and open the SMTP PROXY settings.  Under General Settings category you will see "Set the maximum email size to", set this to preferred size.
