When we do a quick reply to a user's ticket (usually to get clarification of a request), the user gets the email just fine.  However, the reply-to address is the default one that was setup for the helpdesk.  (in our case that is ServiceDesk@ourdomain.com)

However, we want the reply-to address to be the technician that the ticket was assigned to, or the one replying (either is fine).

We know we can setup pop3 or IMAP, but really would like to know if the above can be done?
