Vacation e-mail allows you to let senders know that you are away and not reading your e-mail regularly. It will not stop e-mail from being sent to you.
To set up vacation e-mail, login to the EGR Account page and select the Vacation mail button. This will allow you to enter a message or auto-response which will be sent to those who addressed e-mail to you. You can then select Enable Vacation e-mail to enable it. When you want to disable your vacation e-mail, return to the same site and select Disable Vacation E-mail.
