This is one of many sites we work on, and it appears that on the sites that have been updated to Akeeba Backup 3.10.2 (as opposed to 3.10.1) the "--quiet" option on the cron command is no longer being respected and the cron mailer is sending success as well as error emails.
The 3.10.1 sites are still only sending error and warning emails.
A Success email, used to be blocked by using the "--quiet" option:

A more typical error message (from a different site):

(the error email above is just for comparison).
Did the "--quiet" option change, or do you think this may be something with the host? Since the 3.10.2 sites are the only ones experiencing this, I thought it may be related to the upgrade.
Thank you!
