Email sending limits are important for preventing spam, protecting server reputation, and maintaining email deliverability. In DirectAdmin, you can control how many emails an account, domain, or user can send within a specific time frame.

This guide explains how to change the email sending limit step by step.

What is Email Sending Limit?

The email sending limit defines the maximum number of outgoing emails that can be sent per hour (or per day, depending on server configuration).

For example:

• 50 emails per hour

• 100 emails per hour

• 1000 emails per hour

If the limit is exceeded, further outgoing emails will be temporarily blocked.

Method 1: Change Email Sending Limit as Admin

Only Admin-level users can modify global email sending limits.

Step 1: Log in as Admin

Access your DirectAdmin using:

Login with your admin credentials.

Step 2: Navigate to Admin Settings

From the Admin dashboard:

• Click on Admin Settings

• Locate the email sending limit section

Step 3: Adjust the Global Email Sending Limit

Look for options like:

The new sending limit will now apply based on your configuration.
