Summary
To get delisted from Spamhaus, the consensus emphasizes a multi-faceted approach centered around identifying and rectifying the root cause of the listing and ensuring complete cessation of spam-related activity. The process involves thoroughly reviewing sending practices, enhancing list hygiene by removing inactive subscribers and managing bounces/complaints, and securing servers. Understanding the specific listing type (SBL, PBL, XBL) dictates tailored procedures, and if listed on the PBL, using an authenticated outbound mail relay service is critical. Proactive measures include implementing robust authentication protocols (SPF, DKIM, DMARC), establishing feedback loops with ISPs, and testing emails with tools like Mail-Tester. Regular monitoring of sending reputation via Google Postmaster Tools and similar services, coupled with the use of suppression lists to exclude known complainers, contributes to maintaining a clean sending record. Finally, patience and persistence are required throughout the delisting process, along with meticulously documenting and providing evidence of improved practices when requesting delisting through Spamhaus's website.
