If you oversee an organizations' domain petting zoo, we strongly recommend implementing (in addition to the robust monitoring, compliance and internet asset decommissioning procedures you undoubtedly have in place 😉) periodic checks against Spamhaus DBL – particularly for domains outside your control, such as third-party services used as CNAME targets. Any DBL listing indicates an ongoing abuse incident, and should prompt an investigation. 2/3
