- Enter the message that you would like to have in the auto-response.
- Set the response to auto mail every message
- The default response is every one week to send an auto-reply, for our use it is important to reply to every email.
- NOTE: It is important to understand this command sets the auto-reply delay. Using the -r 0 sets the vacation program to reply to EVERY message it receives. In a production environment, this is not recommended as it can create mail loops.
- Test your reply message from the CLI mailutils package or the MTA chosen to use on client computers
sudo apt install vacation
vacation
nano vacation.msg
vacation -i -r 0
Auto Maildir Clean Up

sudo nano <scriptname.sh>

sudo chmod +x <sciptname.sh>
