Similar to CMD_EMAIL_ACCOUNT_QUOTA and CMD_CHANGE_EMAIL_PASSWORD such that the user can setup his own vacation message without needing a DA account login/password. Practial implementations of all 3 of these commands would be something like a squirrelmail module. This is an api only command. The 4 things you can do are: action=create action=modify action=delete and no action at all to show the current message and dates. For info on how to use these 4 commands, the options passed are exactly the same as the ones passed through DA's interface. Thus, use the same options/return values as for: CMD_API_EMAIL_VACATION http://www.directadmin.com/features.php?id=348 except.. that you must also pass: user=bob domain=domain.com password=secretpass for all commands so it can authenticate.
