Passlist
Also known as an allowlist (formerly whitelist), passlists are lists of email addresses, IPs, and domains that are allowed to bypass certain security measures, such as spam filters.
Passlists work by suppressing addresses and domains from any false positive block listings and permitting them to the inbox. Passlisting is an effective security measure to manage which domains have access to send messages to a specific inbox.
