When you are away from your email for an extended period of time, you can set up vacation mail to alert those who send you mail that you are unavailable. While vacation mail is enabled, anyone who sends you mail will receive an automatic reply that you are not available. You can customize the message sent in the auto reply. To set up vacation mail:
You can use the default auto-reply message or change the Subject and Message Text to something of your liking. When finished, click Set up Vacation processing.
As soon as you enable auto-reply, people sending mail to your mail box will automatically be sent a copy of the response you entered (one per week if you enable longer than that).
