Message Level setting to skip dead lettering
Topic/Queue can have dead lettering enabled. But out of messages sent to the entity, some messages are data sensitive and should be removed even though message body is encrypted due to legal implications. Similar to TTL, an option on message to skip dead lettering is useful here.
One Approach is to auto forward to common topic and skip processing by configuring SQL filter. But if namespace has thousands of entities, it is little overhead.
