Domain reputation for mailfilters

In addition to IP-based reputation contained in the DNSBLs, Spamhaus researchers maintain constantly updated domain-based blocklists. These use multiple sources to define whether domains are involved in malicious activity, or hosting harmful content.

Domain-based reputation data is compiled from a range of live sources including information on bad domain neighbourhoods; DNS glue records; WhoIs records, domains on hold and short-term expiry dates; Alexa web traffic activity data; and temporal data showing brand new domain registrations and new senders of web and email traffic.

These datafeeds are combined to provide mail administrators and network managers with up to the minute data on harmful domains. This river of data, constantly updated, helps to protect network users from traffic from newly identified domains that are associated with phishing, bot-herding, spyware and ransomware attacks.
