First you have 2 cron jobs entered for the same file (cron.php). Apparently for 2 different email addresses.
Definitely delete 1 of them.
Second Remove the:
MAILTO=... (first part in your screen shot)
And Third Remove the:
Next (after cron.php in your screen shot)
Don't know why either are there.
It should look like this:
* * * * * cd /home/i*t*e*/***por***cru***test.com/periodic; /usr/local/bin/php -q cron.php
Or:
* * * * * cd /home/i*t*e*/***por***cru***test.com/periodic; /usr/bin/php -q cron.php
Note:
I *** out part of your cPanel user and domain name in the above examples.
Mailto can be set up further in the cPanel cron jobs in the "Email" area with the "Update Email" button. You don't add it to the actual cron command in cPanel cron jobs. If you do add an email address, don't include the mailto= part in cPanel only the email address, and you can only add one up further.
Not sure where the Next even came from either. My guess is you copy and pasted from the Dolphin installer and copied too much by including the next link/button in the Dolphin installer.
