One of the big revolutions in antispam was reputation-based, which is used in all large email providers. Effectively, every email domain gets a reputation based on their email history. Someone like @gmail.com that sends a lot of mail to the server that isn't spam is going to get through easily. Someone like @spammymcspamface.com that sends naught but spam is going to get black holed. Someone like @whoami.com who hasn't sent anything is going to get throttled until they can establish a reputation as not-spammy.
- danrl 5y agoReputation is, however, not weighted by data tied to the individual receiver's mailbox. Reputation is often tied to the sending domain. Reputation, as helpful as it is, doesn't tap into the data that currently remains largely untapped.
