Using RBLs (Real-time Blackhole Lists) and ORDBLs (Open Relay Database Lists) is 
an effective way to tag or reject spam as it enters your system. These lists act as 
domain name servers that match the domain of incoming email to a list of IP 
addresses known to send spam or allow spam to pass through. RBLs keep track of 
reported spam source addresses and ORDBLs keep track of unsecured third party 
SMTP servers, known as open relays, which some spammers use to send unsolicited 
bulk email.

There are also several free and subscription servers available that provide reliable 
access to continually updated RBLs and ORDBLs. Check with the service you are 
using to confirm the correct domain name for connecting to the server.

The FortiGate unit communicates with RBL servers using UDP through port 53. The 
FortiGate unit compares the IP address or domain name of the sender to any 
database lists you configure. The FortiGate unit checks all the servers in the list 
simultaneously. If a match is found, the corresponding protection profile action is 
taken. If no match is found, the email is passed on to the next spam filter.

The action to take on email from the configured IP address. Actions are:

Reject (SMTP only) to drop the session.
