As a cPanel/WHM administrator I would like to see notifications for cPanel and WHM be sent over an authenticated SMTP connection. This would help prevent these (sometimes) important notifications from ending up in spam or junk folders.
Improve deliverability of emails coming from firstname.lastname@example.org
As a server administrator I would like to be able to configure the 'From' address for all cPanel notifications, allowing me to chose the best solution for any user that isn't hosting email locally, and prevent them from losing notifications sent by the server for failures with regard to SPF and DMARC.
case CPANEL-16733: Make cpanel@ emails pass sender verification
case CPANEL-15185: Ensure cpanel@ emails can pass DKIM/SPF/DMARC for the hostname of the server
case CPANEL-?????: Consider making cpanel@ use SMTP authentication in order to have a esmtpsa transport method in the header to improve deliverability
