In my testing, this worked as advertised. Changing the "MAILTO=" in
/etc/crontab from the default "root" to either a local username or a
remote address resulted in the crontab messages being delivered to
the desired mailboxes. I think I'd put a test command into the
crontab and watch the logs to see what might be going on -- including
making certain that the crontab is reloading correctly after changing
the "mailto" value.

Separately, but related, did you run newaliases or postalias after
you added the entry to "root:" in /etc/aliases?
