Ability to block emails from recipients that are in a certain mail list
Let's say I have a maillist on my Plesk for Windows server that sends emails to some external users.
I want a built-in ability to block emails from certain recipiens that are in the mail list.

We understand that you are seeking the ability to send mass emails but do not wish to receive replies from your target audience. To achieve this you can set your sender address to a non-existent mail address and configure your mail settings that emails directed to a non-existent mail address are rejected.
