Summary
When a domain is blocked by Spamhaus, the primary focus should be on identifying and rectifying the issues causing the listing, which commonly include sending unsolicited spam, having compromised servers or accounts, or practicing poor list management. Addressing this involves halting email campaigns immediately, improving domain reputation by auditing email lists, implementing double opt-in, authenticating emails using SPF, DKIM, and DMARC, and improving list hygiene. Leverage tools like Microsoft's SNDS and Google Postmaster Tools to monitor your sending reputation and identify problematic patterns. Actively clean your email lists and prevent bad traffic by validating user emails. Avoid 'trap hunting' and focus on overall sending quality. Contact Spamhaus for delisting only after fully resolving the issues and be prepared to provide detailed evidence of the corrective actions taken. For ESPs, educating clients on email best practices is crucial, and setting up feedback loops with ISPs aids in prompt identification of spam complaints. Gradually warming up sending volume helps establish a positive reputation and prevents being flagged as spam. It is also essential to prioritize ethical practices, and if working for a company that knowingly spams, consider seeking alternative employment.
