Not sure if this will help or not. I use webmin to administer a server and have used it to create several cron jobs with the option to send an email for each job.
You may be able to manually edit your cron jobs in /var/spool/cron as root. The cron jobs will be listed in files named for the user who runs the jobs.

In the following examples, I have 2 cron jobs, the first of which runs a script every 5 minutes to pipe various commands through cat to create a text file... the second job mails that text file to a user every 4 hours. BUT, on the second job, piping cat to mail to the user is part of the command I assigned as a cron job.

0,5,10,15,20,25,30,35,40,45,50,55 * * * * sh /home/username/Documents/uptime.sh   #Write system uptime to text and html
0 1,5,9,13,17,21 * * * cat /var/www/html/uptime.txt | mail username at domain.com    #Mail uptime.txt to username

I have other cron jobs which send results through email, but the mail command was not part of the command issued, rather it was defined by webmin when I set up the jobs. I cannot find where cron has saved that mail info for those jobs.
