I am trying to familiarize myself with crontab. I know that it is supposed to send an email containing the output of jobs to the user that scheduled them however, I can see in the syslog that the address crontab is sending emails to is not a "local" one (as if I were to type mail -s "email here" username) but an external email address (like [email protected]).
Can someone tell me from where this email is derived and how I can set the users' email address to something else?
This could be because I have a top-level domain associated with my instance (I can see in the log the emails are being sent there), however, I actually have two domain names pointed to this server so I don't know how crontab is choosing or what would happen if there were no domain on this machine.
In short I am just trying to figure out where this default email address is set.
man 5 crontab
If MAILTO is defined (and non-empty), mail is sent to the user so named. MAILTO may also be used to direct mail to multi‐ ple recipients by separating recipient users with a comma.
