crontab MAILTO="" is not working

**jay98** · July 13th, 2015

Before anyone gets too incensed, please know that I have googled this and have yet to find a viable or applicable solution. So...
I am running Ubuntu Server 12.04, and run tripwire every morning. I have a tripwire report emailed to me, but a copy of that report is also emailed to the root account on that server, and I cannot stop these emails.

Running

Code:

sudo crontab -e

my crontab looks like this:

Code:

MAILTO=""
0 5 * * * /usr/sbin/tripwire --check | mail -s "Daily Tripwire Report" me@mydomain.com

Am I setting the MAILTO variable incorrectly?
Any thoughts on stopping the local email to root but still receiving the external email?

Thx

From here: http://unix.stackexchange.com/questi...ob-to-dev-null

try redirecting all output to /dev/null
0 5 * * * /usr/sbin/tripwire --check | mail -s "Daily Tripwire Report" me@mydomain.com > /dev/null 2>&1

Thanks, I'll give it shot. I actually thought about this, but wasn't sure if /dev/null would squash the email I did want. Will let you know...

If the /dev/null squashes even the content of the email, then move your cron commands to a script file, then trigger the script using cron. Something like:
0 5 * * * /bin/bash /my/tripwire/script.sh > /dev/null 2>&1

Then the contents of the script.sh is:

Code:

 #!/bin/bash
/usr/sbin/tripwire --check | mail -s "Daily Tripwire Report" me@mydomain.com

This did not work

I actually got both emails; the email to me@mydomain.com, and the email to root on that box.
MAILTO="" and redirecting output to /dev/null 2>&1 are ignored completely.

I am editing cron with

Code:
