Hi there, want to ask if there's a feature where i can block emails from outside world being sent to one of our internal email?

Let's say :
tm@abc.com which we only use internally and served as an alias. Any emails from outside world sent to tm@abc.com will be blocked, but any email ended @abc.com can send to tm@abc.com.

Can this be done?

Thanks.
