Anti-Spam Server for MS Exchange – RBL
Getting here: Main Screen -> Main Menu Tools -> Advanced settings -> Server components -> branch Anti-Spam Server for MS Exchange -> RBL
RBL (Real-time Blackhole List) server is a DNS server with an extensive database of known spam senders. When this feature is switched on, all e-mail messages will be verified against the RBL server database, and marked as spam if identical to any of the database entries (no personal data is sent over to the server!). The databases contain the latest up-to-the-minute spam fingerprints, and therefore provide the very best and most accurate spam detection.
By default, the online checking feature is turned off. Check the Query RBL servers box to activate it.
The RBL servers list text field allows you to define RBL servers locations. If you wish to turn the feature on but are not sure about specific RBL servers addresses, we can recommend the following:
If you want to use both (or more) RBL servers, divide the addresses by commas or semi-colons, with no extra space. Port numbers should be entered after a double colon, as seen in the example.
