Hi,

While I hate to copy things from linux, I have found this additional
variable to be useful, especially in root's crontab:

MAILTO=admins at foo.bar.com

I know you can just alias root to the other mailing list in
/etc/aliases, but since this works for all  the jobs that follow it
and can be listed more than once, it does allow different jobs to be
mailed to diferent lists.

Before I discovered this, I did what another user mentioned, and just
made the script send the mail itself. Which works, but ends upwith a
lot of repeated code - especially if you want logic to only send mail
when there is output.
It's nice having that logic centralized in cron.
