My cPanel/WHM mail server for [login to view URL] keeps landing on the Spamhaus blocklist and mail flow stops every time it happens. The stack is straightforward—IBM hardware → VMware ESXi → AlmaLinux VM running WHM/cPanel—all hosted in our own data-center. I have already opened tickets with Spamhaus, but the listing returns as soon as they clear it, so the root cause clearly sits on our side. static IP we bought from Airtel What I need from you is a thorough audit of the server and its surrounding network to identify exactly why Spamhaus keeps flagging us and then to implement a lasting fix. That may include reviewing rDNS, SPF, DKIM, DMARC, HELO practices, outbound filtering, queue hygiene, firewall rules, and any reputation or relay issues you discover. If you spot configuration weaknesses in WHM or cPanel, please harden them and document what you change. Deliverables • Written report summarising the findings and root cause • All configuration changes applied (with before/after details) • Confirmation that [login to view URL] and its sending IP pass Spamhaus re-check without warnings • Simple post-resolution checklist I can follow to prevent a relapse I am happy to grant full root and WHM access inside a maintenance window you suggest, and I can provide Spamhaus ticket references if they help. Once you are done, the server must be clear of blocklists and able to send mail reliably.

Hello, I have 10 years of experience in managing and optimizing WHM/cPanel environments. I propose to conduct a comprehensive audit of your server and network to identify why Spamhaus lists dcit123.in. I will examine rDNS, SPF, DKIM, DMARC, HELO, and firewall settings. All findings and changes will be documented, ensuring the Spamhaus re-check passes without warnings. The server will be cleaned and capable of reliable email delivery. Regards, VishnuLal NB*

Hi, I have 5+ years of experience working with Linux servers and cPanel environments. Recurring Spamhaus listings usually point to outbound spam, compromised scripts/accounts, or incorrect mail configuration. I can perform a quick audit of your server (mail queue, Exim logs, DNS records, and security) to identify the exact root cause and apply a permanent fix. To ensure a complete resolution, I’ll need: • Root SSH access and WHM access • Control over DNS (SPF, DKIM, DMARC) • rDNS/PTR configuration from your ISP (Airtel) • Dedicated IP (not shared hosting) Without these, a reliable and permanent fix may not be possible. I’m available to start within a maintenance window. Thanks

Hola, Puedo ayudarte a identificar y solucionar el problema de blacklist en Spamhaus de forma definitiva. Entiendo que si la IP vuelve a listarse después de ser removida, el problema está en la configuración del servidor o en el flujo de salida de correos. Mi enfoque será: • Auditoría completa del servidor WHM/cPanel • Revisión de SPF, DKIM, DMARC y rDNS • Verificación de HELO/EHLO y reputación de IP • Análisis de colas de correo (mail queue) • Detección de posibles scripts o cuentas comprometidas • Revisión de firewall y control de salida SMTP • Implementación de medidas para prevenir futuros bloqueos También documentaré todos los cambios realizados y proporcionaré una checklist simple para mantener el servidor limpio a futuro. Estoy disponible para trabajar con acceso root dentro de la ventana de mantenimiento que prefieras. Quedo atento.
