The Spamhaus Whitelist has strict eligibility criteria but one rule stands out above the rest and that is: Absolutely no marketing or soliciting bulk email of any sort.
Unlike traditional whitelists, the Spamhaus Whitelist is not a service to help bulk mail senders improve delivery rates. You can not whitelist an IP address or domain that is used for sending marketing or soliciting bulk email, or used for sending any email on behalf of third patries. This rule therefore automatically excludes (makes not eligibile for whitelisting) Email Service Providers, ISP customer mail relays and mail servers used by third-parties, and all bulk mailing list servers and services.
The Spamhaus Whitelist operates a policy of ‘Know Your User’, which means that owners/operators of mail servers elegible for whitelisting must know their users personally, either because all users are part of the organization that operates the mail server or are company machines (such as ecommerce servers).
