Once inside cPanel, scroll down to the Email section.
Click Autoresponders.
Fill in the required details:
Character Set: Leave it as utf-8 (default).
Interval: Set how many hours to wait before sending another auto-reply to the same email address.
Email: Enter the email account you want to set up (e.g., support@yourdomain.com).
From: The name that should appear in the reply (e.g., “Support Team”).
Subject: The subject line for your automatic reply (e.g., “Thank You for Contacting Us”).
Body: Type your auto-response message here. You can use plain text or HTML.
You can schedule your auto responder to run only during a specific period — for example, during holidays or out-of-office dates.
Set the Start time (immediate or custom date/time).
