Add hidden mail forwarding option
There should be an option to forward mail without letting the customer know it is enabled (to the extent permitted by the law).
Currently, it is possible to hide all mail settings from a service plan or subscription. More granular control to hide mail forwarding only, or an option to enable it separate from the customer's own forwarding settings, would help monitor malicious content.
Plesk Tech Support shared this idea
No information in which jurisdiction hidden mail forwarding (without the customer knowing about it) is allowed. As Plesk supports legal use only, we must decline this request.
