Why each option
While FortiGate devices offer robust email filtering capabilities including IP reputation, URL/email address content filtering, and spam object checksums, greylisting is not a native or configurable email filter option on the device.
FortiGate units utilize sender IP reputation databases (e.g., FortiGuard AntiSpam) to identify and block spam based on the sender's IP address reputation.
FortiGate can detect and block spam based on URLs found within the body of an email that are known to be associated with spam or malicious content.
FortiGate can identify and filter spam based on email addresses contained within the body of a message that are recognized as spam-related.
Spam object checksums allow FortiGate to detect known spam variants by comparing hashes of email content against a database of known spam signatures.
Spam greylisting, which temporarily rejects emails from unknown senders and requires a retry to accept them, is not a native email filtering method directly available or configurable as a spam feature on a FortiGate unit.
