BSD periodic can no longer satisfy my needs, so I switched to Vixie cron last week, and also got started with system mail. (Of course periodic can also mail results, but I never took advantage of that.) I'll list the things I've learned about mail thus far.

Warning: Here are things I've learnt on OS X 10.9. YMMV on other systems.

1. It's easy to let cron email output to you. Add to your crontab

    MAILTO=torvalds,torvalds@klaava.helsinki.fi
   

   As in the above example, you can either specify a local user, e.g., torvalds, or an actual email address, torvalds@klaava.helsinki.fi. Do separate email addresses with a comma. Do not add an extra space. See man 5 crontab, though you might not find the tip above.
