Ah ha, okay. Yeah, just copy/paste into crontab, should be all set.
You'll want to run manually first and see if the emails come through. I tested on a FreePBX system and it went straight through to my Office 365 no problem.
If you are on FreePBX, you will need mailx installed. All dependencies are met by a default install. It's a tiny binary package.
yum -y install mailx
That is what provides the mail command.
