Real-Time Block List Service

Real-Time Block Lists are a very useful security service for clients who wish to cut off email contact with servers that are associated with extensive spamming.

It is an especially useful service for clients who run their own mail servers, as it gives the server the power to shield itself against highly troublesome IP ranges.

To prevent these servers from interacting with a client’s mail server, a range of IP addresses are supplied to client institutions, who can then block these ranges. This results in the refusal of incoming emails from this range of suspect IPs, ensuring no contact is possible.

HEAnet’s Real-Time Block List Service is available to all clients and is offered in partnership with TrendMicro.com and SpamHaus.org at no extra cost.
