Following up on your problem.

I am unsure why MAILTO is failing.

According to man 5 crontab

"If MAILTO is defined (and non-empty), mail is sent
       to the user so named.  If MAILTO is defined but empty
(MAILTO=""),  no
       mail will be sent."

Maybe someone more knowledgeable can chime in.
