1. Login to your cPanel
2. In the Email section, find and click on Email Accounts.
3. Locate the email you want to set an auto-responder for and click Manage on its right.
4. Click on the Send Automated Responses.
5. Click Add Autoresponder to create a new one, or click Edit under Current Autoresponders to modify an existing one.
6. Configure the Auto Responder:
-Character Set: Leave this as default unless you need a specific character set.
-Interval: Set how many seconds the auto-responder should wait before sending another response to the same sender (to prevent spamming).
Typically, you can leave it as the default (usually 24 hours).
-From: Enter the name and email address that will appear as the sender of the auto-response. It’s usually best to leave this blank so it uses the default sender settings.
-Subject: Enter the subject of your auto-response email (e.g., "Out of Office" or "Thank you for your email").
-Body: Write the body of the auto-response message. This is the text the sender will receive when they email you.
-Set Date Range: you can choose to set a start and end date for the auto-responder, or you can leave it open-ended for an indefinite duration.
7 Once you've entered all the necessary information, click Create/Modify.
