Delete mails addressed to non-existent mail addresses, do not reject, but route them to null
Create a new option for mail to nonexistant mail in a domain, an option that allow discard this kind of mails. Actual options can cause unlimited bouncing if sender domain doesn't exist.

I am getting blocked by very sensistive Microsoft controlled domain servers because of backscatter caused by replies no user here. It is a paind to get delisted, as their SNDS page reports no issues with the IP. No other blacklist does this.
The system is not set to bounce no user emails, that would be a terrible idea but it does reply no user here.
It would be better of Plesk could have to option to silently accept those email address that do not exist on the server send to them to blackhole like /dev/null
Currently all we can do is empty a forwarding email box. A fix is rather urgent
