No cron emails to root?

[oz42]

Hi,

Since I upgraded to 10.1, I see this in the logs

Dec 13 14:00:00 igor postfix/sendmail[6642]: fatal: root(0): No recipient addresses found in message header

I assume that cron is not working well. I have added a

MAILTO=root

to /etc/crontab and root's crontab, still no luck. The security emails still arrive.

Any ideas?
