[otrs] Manage Queue-Auto Response Relations

Hi After solving the POP3S problems, Now my new otrs installatino is working with a couple problems : 1. How to manage AutoResponse to Queue, I go to Admin >> Queue-Auto Response Relations but I have no idea how to do next, I tried to send email to support email, ticket is created, and admin get notificatin about this ticket. But user did not receive any auto response. Some thing is missing? 2. In Agent notificatino, I get something like this : https://yourhost.example.com/otrs/ How to change this settings? Sorry I tried to look at http://doc.otrs.org/3.0/en/html/ but not found any answer Is there any How To Docs or ebook available? Thanks Yuan ------------
