[otrs] Dynamic note for close ticket notification ?

hi, i am new to otrs (otrs 2.3.4 on a centos 5.2.) our requirement is when a agent close the ticket, notification should be sent to the sender of the ticket(Customer) & the notification should be the note that was written while closing the ticket. close ticket notification with predefined static note(*** THIS IS JUST A NOTE *** The state of your ticket...............) is working fine. but what about the dynamic note, any configuration changes. thanks in advance, -- regards: Amanpreet Singh
