Airstack spam filters

Learn how to create a split inbox with Airstack that filters senders into three buckets: Primary, General, & Requests. The goal is for the user to never see any spam messages.

• Primary Inbox: The Primary Inbox should contain all the users that a given user certainly knows.
• General Inbox: The General inbox should contain all the users that a given user is likely to know or we have strong signals that they are a good actor.
• Request Inbox: The Request Inbox is for users unknown to the main user and without any connections. It typically holds spam, which users should avoid.
