Why each option
FortiGate units support a comprehensive range of spam filtering methods, including reputation checks, DNS verifications, content analysis, and administrator-defined black/white lists.
IP Address Check is a supported method where FortiGate uses FortiGuard IP reputation databases to identify and block spam sources based on their IP addresses.
Open Relay Database List (ORDBL) is supported to identify and reject emails originating from mail servers configured as open relays, which are often exploited by spammers.
Black/White Lists are supported, allowing administrators to define specific sender or recipient email addresses and domains that should always be blocked or always allowed, respectively.
Return Email DNS Check is supported to verify the sender's domain using DNS records like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to detect email spoofing.
Email Checksum Check is supported to identify and block duplicate spam messages by comparing the checksums or hashes of email content against known spam signatures.
