Spamhaus and SURBL BV Considered to be Best Practices Approach to Fighting Spam.
The use of Spamhaus, the #1 anti-spam block list, and SURBL BV, a leading domain blocklist, are considered best practices when it comes to email filtering services and fighting spam.
Two-Stage Filtering
Phase 1: IP-Based Email Filtering
The first stage of email filtering looks at the sender’s IP address. Real-time threat intelligence feeds are used in this first stage to identify and block known malicious IP addresses. If the email sender’s IP address is included in threat intelligence blocklist, the policy decision will tag or reject the message.
Using IP blocklists, like the ones below from Spamhaus, stops known malicious IP addresses from sending messages to email users. IP blocklists are the most effective first line of defense against spam, botnets, malware, ransomware, and more. Spamhaus offers the #1 anti-spam IP blocklists, blocking up to 95% of spam messages with <0.02% false positives.

Phase 2: Domain and Content-Based Filtering
The second phase of email filtering checks domains and content contained in the body of the email message.
Email filters check these domains against domain / content-based threat intelligence feeds. Domains included in the blocklist are known to be involved in malware, phishing, spam and other cyber threats.
Domain-based blocklists identifies what type of cyberthreat the domain is involved in when the mail server or spam filter queries it, allowing policy decision to reject, tag or accept the message.
Ongoing Innovation: Latest techniques also allow email filters to block based on email content / hashes. Hash blocklists are new effective method at identifying and filtering cryptocurrency addresses, malware files, email addresses. Hash blocklists are also used to block malicious domains hiding behind re-directors or shortened URLs, often missed by IP- or domain-based blocklists.
