I've been using `MAILTO=""` in the system crontab for years, seems to work 
well (I just get spurious messages "mailed 1 byte of output but got status 
0xffffffff" in logs, not sure if they are related).

This didn't work with the old `atrun`, which was then fixed as a side-effect 
of integration into `cron` (by the way, the `atrun` manpage in 12 still does 
not reflect it).
