Security Checklist Before IP Delisting
- Scan your server using trusted security tools such as ClamAV or RKHunter to detect and remove malware.
- Monitor server processes and logs to identify suspicious or continuously running scripts.
- Locate and remove unknown or injected files inside compromised hosting accounts.
- Always keep CMS platforms like WordPress, Joomla, Magento, and OpenCart updated to the latest versions.
Once your IP is delisted, take preventive steps to ensure the issue does not occur again. Schedule monthly security scans, monitor Apache logs, mail queues, and SMTP activity, and suspend any account that abuses server resources.
