Abnormal has enhanced Inbound Email Security's detection model by leveraging behavioral intelligence that identifies more known-good behaviors to identify anomalies in emails that indicate spam. For example, older domains are less likely than young domains to be carrying out this newer type of spam we are now filtering out of inboxes.
Inbound Email security now filters twice the volume of spam to a hidden folder, freeing security analysts from having to triage additional user-reported spam reported to their abuse mailbox.
