Create a server rule in the server config document like this:

If sender contains

AND

any recipient contains

Then

change routing state

This way the router will hold these messages in the mailbox where you can make sure that the rule is working as desired by looking at them and deleting them - later on you can set the rule to just ‘don’t deliver message’
