Introduction

This guide covers how to set a daily email quota limit on a DirectAdmin hosting server. It is intended for server administrators who want to control the number of emails that users can send from their accounts. By implementing this limit, administrators can manage email traffic, reduce the risk of server blacklisting, and prevent abuse, such as spam or bulk email sending. The quota can be applied either globally for all users or individually for specific accounts.

This guide will also address a common issue where users may encounter a limit block when trying to send emails. This can occur when users exceed their daily email quota, resulting in email sending restrictions. Understanding how to manage these limits effectively can help in maintaining a balanced and secure email environment on your server.

Prerequisites

• SSH access to the server.
• Basic familiarity with Linux commands and file editing.

Step-by-step guide

Step 1: SSH into the server

1. Open your terminal and log in to your server via SSH:

ssh root@your_server_ip

2. Replace your_server_ip with your actual server’s IP address.

Step 2: View and modify the global daily email quota

1. To modify the global daily email limit, edit the limit file by running:

vi /etc/virtual/limit

2. You will see the current daily email limit. Change the value to your desired limit (e.g., 1000 emails per day) and save the file.

Step 3: Set an individual email quota for a specific user

1. To set a custom email limit for a specific user, create a new file for that user by running:

echo 1000 > /etc/virtual/limit_username

2. Replace username with the actual username and adjust the limit (e.g., 1000 emails per day).

Conclusion

By following these steps, you can easily manage and control the email sending capabilities of all users or specific users on your DirectAdmin server. This helps in maintaining efficient email management and preventing potential email abuse.
