Reactivating console mail logging from cronjobs on macOS server

I am running several cron jobs on a Mac server. Some time ago I don't know why I deactivated the cron logs into the local mail of the system. I now am getting errors running those cronjobs and I am not able to take a look at the logs as they are not generated.



Is there a way to reactivate this behavior?



I tried adding this line on top of the cronjob definition file, cronjob -e


MAILTO="/var/mail/MY_USERNAME"


With no result, previously whenever a cron ran I was getting on the console a message indicating that I had new mail as the result has been appended to the mail. I can't seem to reactivate this behavior and when I open `mail` from console the inbox is empty.
