# How to Configure CWP server for Email use

Configuring your **CWP (CentOS Web Panel)** server for email use involves setting up the necessary services like **Postfix**, **Dovecot**, and ensuring that proper DNS records are configured (such as **MX**, **SPF**, **DKIM**, and **rDNS**). This guide will help you set up email services on your CWP server, allowing you to send and receive emails via your domain.

- **Root access** to the server.
- A valid **domain name** pointing to your server.
- **rDNS** (reverse DNS) configured for your server's IP address (if not, contact our **[support team](https://wa.me/19726743814)** to set it up to point to the server's hostname then give it 3 hours to propagate. before proceeding). This is important.

**Step 1: Log in to CWP Admin Panel** using [these](https://truehost.com/support/knowledge-base/how-to-access-cwp-main-whm-panel/) steps

**Step 2: Configure hostname SSL for your server**.

This SSL Certificate will allow your webmail to be accessible via https and will also be used for TLS/SSL encryption for your emails

- If you did not, during CWP Installation, please configure your hostname using **[these steps.](https://truehost.com/support/knowledge-base/set-up-hostname-ssl-on-cwp/)**

**Step 3: Configure SPF** **Record**
