For each e-mail account you can switch on the automatic response
service which will send a predefined e-mail message in reply to any
incoming e-mail message. This is useful for sending "out of office" or
"on vacation" notices when you are away.
1. Click Mail.
Choose the e-mail address where you will be setting up the auto-responder.
2. Go to the Auto-Reply tab.
3. Select the Switch on Auto-Reply checkbox.
4. Specify the subject message format encoding, and message text.
5. Set an address where incoming messages will be sent.
6. Click OK.
That's it! You now know how to set up an auto-responder in Plesk.
