I have cron working on a single-user Fedora22, and am trying to make the cron send emails.
This is my crontab:
*/10 * * * * /home/wolfv/backup_script /home/wolfv /home/wolfv/backup_local
44 00,12 * * * /home/wolfv/backup_script /home/wolfv gs://wolfv
cron runs the script as scheduled but does not send emails.
So I add a MAILTO line as described in https://wiki.archlinux.org/index.php/Msmtp#Cronie_default_email_client
MAILTO=redact@yahoo.com
*/10 * * * * /home/wolfv/backup_script /home/wolfv /home/wolfv/backup_local
44 00,12 * * * /home/wolfv/backup_script /home/wolfv gs://wolfv
cron runs the script as scheduled but does not send emails, and does not leave an entry in the .msmtp.log.
My msmtp is working. This sends email and leaves an entry in the .msmtp.log:
$ cat test.mail | msmtp -a default redact@yahoo.com
How to make cron to send emails?
UPDATE: I got cron to send emails another way. Now I am trying to get cronic to work. Here are the results:
Explicit cronic path and msmtp for specific cron jobs
13:50 crontab, crontab with cronic, no email, backup worked:

With MAILTO
14:40 crontab, no email, backup worked:
MAILTO=redact@yahoo.com
\*/10 * * * * /home/wolfv/backup_script /home/wolfv /home/wolfv/backup_local
Interestingly, this is the only journalctl entry that detected the error I planted in backup_script: line 17:
$ journalctl --since 14:40
Jul 29 14:40:01 localhost.localdomain CROND[20390]: (wolfv) CMD (/home/wolfv/backup_script /home/wolfv /home/wolfv/backup_local)

Nothing in journalctl -u:
$ journalctl -u crond --since 14:40
Nothing in .msmtp.log
I would still like to get MAILTO working.
But more importantly, I would like to get cronic to send emails.
I was going by the cronic documentation on http://hackersome.com/p/benjaminoakes/cronic and http://habilis.net/cronic/
