If your server is configured to support server-side mail rules, you can set up vacation notices. If you enable vacation notices, if someone sends you an email during a specified period of time, an email is automatically sent to them. If they send you multiple emails in a day, they are sent a single vacation notice email that day.
If you're away from your email for an extended period of time, setting up a vacation notice is a good way to inform people of your unavailability and your expected return date.
To set up a vacation notice:
While viewing My Page, click "settings."
Select Vacation Notice.
To enable vacation notices, for Enabled, select On; to disable vacation notices, select Off.
Click the date next to Vacation Begins and then select the date when notifications will start being sent.
Click the date next to Returning On and then select the date when notifications will stop being sent.
In the Email Subject field, enter the subject line of the email that will be sent.
In the Vacation Message area, enter the body of the email that will be sent.
