After checking Mail Delivery Reports, I can see that emails are being successfully received to email accounts that don't exist - they are marked as spam, but I would like to see them rejected.
Is this possible?
I've setup a mail gateway using postfix in-front of cpanel to filter spam/virus before delivery to exim.
In postfix i setup "reject_unverified_recipient" so that postfix could verify if the recipient actually exist in cpanel before delivery
below is the config from postfix regarding recipient...
