You should configure your vacation messages from the DirectAdmin control panel.
1. Log into the control panel at http://www.YOUDOMAIN.co.nz/config
Your control panel login and password will have been sent to you in the welcome email when you joined.
2. Under the E-mail Management heading click "Vacation messages"
3. Then click Set Vacation Message. The Set Vacation message screen will display.
4. Change the settings as required:
Make certain that you set the correct email account at the top where it says Vacation Account
Make certain that you set a start date and an end date for your vacation at the bottom where it says Vacation Start and Vacation End. Your vacation message will automatically turn on at the Vacation Start date and automatically stop on the Vacation End date. There is no need to manually turn the vacation message off when you return to work.
