How to Set Up DKIM, SPF, and DMARC in cPanel for Better Email Deliverability

Email deliverability can make or break your online communication. You can craft the perfect message, but if it lands in a spam folder — or gets rejected outright — your effort was wasted. That’s where email authentication protocols come in. DKIM, SPF, and DMARC are three DNS-based standards that tell receiving mail servers that your email is legitimate and not forged by a spammer.

cPanel provides built-in tools for configuring all three. This guide walks through each protocol, how to set them up from your cPanel dashboard, and how to verify everything is working.

A Complete Guide to ModSecurity and WAF Configuration in cPanel

by

If your cPanel-hosted website has ever been compromised, defaced, or used to distribute malware, you know how devastating a security breach can be. Hackers routinely scan for vulnerable applications, outdated plugins, and weak configurations. Fortunately, cPanel includes a powerful first line of defense that many site owners underutilize: ModSecurity and the integrated Web Application Firewall (WAF). Configuring these tools correctly can block the vast majority of common attacks before they ever reach your application code.

ModSecurity is an open-source web application firewall engine that integrates directly with the Apache web server. cPanel provides a user-friendly interface to manage ModSecurity rules, toggle protections, and create custom rule exclusions. This guide walks you through enabling ModSecurity, understanding the rule sets, whitelisting false positives, and monitoring blocked traffic — so you can harden your server without breaking your site’s functionality.

cPanel’s Addon Domains feature is one of the most commonly used tools for resellers, developers, and site owners who manage multiple projects from a single control panel. This guide walks through everything from creating your first addon domain to troubleshooting the most common pitfalls, so you can expand your web presence without expanding your hosting bill.

How to Fix AutoSSL Errors in cPanel: A Step-by-Step Troubleshooting Guide

by

If you manage websites on a cPanel server, you have probably encountered AutoSSL at some point. AutoSSL is cPanel’s automated mechanism for provisioning and renewing free SSL certificates—typically from Let’s Encrypt or cPanel’s built-in Comodo certificate authority. It runs on a daily schedule and attempts to secure every domain and subdomain on the server. When it works, it eliminates the hassle of manual certificate renewals. When it breaks, however, the result can be a confusing wall of warnings in your cPanel interface and, worse, browser security errors for your visitors.

The most common AutoSSL failures include certificates that never provision, domains stuck in “pending validation,” mixed-content warnings after installation, or the dreaded “AutoSSL is currently unavailable” message. Each of these failures has a root cause—often related to DNS propagation, cPanel user permissions, or server-level configuration issues. In this guide, you will learn how to diagnose the most common AutoSSL errors and resolve them without needing to escalate to your hosting provider.
