At the simplest level, create a master list/smart list with those emails you want to suppress. And then include the filter “MEMBER OF SMART LIST - not in - [name or smart list]” in your smart campaigns.
There's no such thing as a system-maintained suppression list in Marketo, Akash. (The system-level Durable Unsubscribe table isn't the same as a broader list of people you will not send to for a variety of reasons.)
As Kevin noted on one of your other threads, you seem to be using terms as if they have one single meaning, and one preexisting technical implementation, in the Marketo ecosystem. In fact, in most cases the business logic is for you to implement as a Marketo owner.
