Vacation is the automatic mail answering program found on many Unix systems. This write up will guide you on how to install and configure the vacation email responder and setup it using the popular webmail SquirrelMail in CentOS 5. Do not use my previous write up as a guide because the SquirrelMail Vacation Local plugin contains dangerous vulnerabilities. You are advised to upgrade to the SquirrelMail Local User Autoresponder and Mail Forwarder plugin immediately.
