Q:
What is RBL and how does it work?
A:
RBL: Real-time Black Hole List
RBL checks the IP address of the machine trying to send against the lists at the RBL sites you enter.
RBL maintains a list of confirmed spammers and open relays. If the mail host matches an entry on the RBL, the connection is refused.
To enable this option, mark Perform Check.
To add an RBL site, enter the IP address or host name of the RBL list server and click Add.
