  • 0


In the world of server management, encountering a "404 Not Found" error is a common scenario. This article is crafted to guide server administrators through the process of troubleshooting and resolving this issue specifically for webmail URLs in the DirectAdmin control panel, leveraging the default setting that recognizes "/roundcube/" as the primary path for webmail.

Section 1: Understanding the DirectAdmin Environment

About DirectAdmin

DirectAdmin is a graphical web-based web hosting control panel designed to make administration of websites easier. Understanding the default settings and paths, such as the default webmail URL being designated to "/roundcube/" is pivotal in troubleshooting issues such as the 404 error encountered during webmail access.

Section 2: Recognizing the Issue

The 404 Not Found Error

When users encounter a "404 Not Found" error while trying to access the webmail through the "/webmail" URL, it typically means that the server couldn't find the requested address. Given that DirectAdmin defaults to using Roundcube and the path "/roundcube/" for webmail, understanding this can often be the first step in resolving the issue.

Section 3: The Solution - Creating a Redirect

Step 1: Login to DirectAdmin

Server administrators should initiate the process by logging into the DirectAdmin panel using the necessary administrative credentials.

Step 2: Locate the Custom HTTPD Configurations

Navigate to "Custom HTTPD Configurations" under the "Extra Features" section to facilitate the redirection process.

Step 3: Setting up a 301 Redirect

At this juncture, it is essential to create a 301 redirect to point "/webmail" to the "/roundcube/" directory, thus resolving the 404 error. Below is a step-by-step guide to set up a 301 redirect:

  • Identify and select the domain in question.

  • In the custom configurations for the domain, add the following redirect rule:

Redirect 301 /webmail

  • Here, replace "XX-XX-XX-XX" with your server's IP address.

Step 4: Restart the Web Server

Post the configuration, save the changes and restart the Apache service to apply the fresh settings. Utilize the command below to restart the service:

systemctl restart httpd

Section 4: Testing the Configuration

After successfully restarting the web server, test the new setup by accessing the "/webmail" URL to verify if it redirects correctly to the Roundcube webmail application.


Through a comprehensive understanding of the DirectAdmin control panel and by leveraging the default paths used by the system, server administrators can easily troubleshoot and resolve the "404 Not Found" error encountered while accessing the webmail URL. Following the detailed guide above will ensure a smooth redirection setup, facilitating seamless access to the webmail services via the "/webmail" URL.
