To disable Email Delivery Route that option would be "Ability to Trace an email address" one in Feature Manager for the feature list. Unfortunately, you would need to issue the following command as this isn't properly being detected when disabled in the feature list currently:
Code:
echo "deliveryreport=0" >> /var/cpanel/features/featurelistname
Please replace
featurelistname with the name of your feature list, so if it were noemail it would be /var/cpanel/features/noemail for the path for the above command.
We have case #47931 about this feature not disabling properly when being deselected in the feature list.
As for the "Import Addresses/Forwarders" option, that is likely the "CSV Import (Email & Forwarders)" one in WHM's Feature Manager for the feature list.
