I followed your instructions, but now cannot send mail to root as you describe in the tutorial. I get the same message as the previous poster, and don't know how to "su" previous to sending mail in the Terminal. All I want is to be able to receive my local mail reporting the cron jobs. Will this still work now that I've followed the above instructions? Could you possibly give us an update on what we need to do to be able to have the same functionality that we had PREVIOUS to the 10.1.5 update???
