Once the client has created a ticket and a copy has been sent to me, I like to be able to use my Emails to respond to the client directly and have all my responses to be part of the ticket. In other Ticketing system, the ticket number is always in the subject line and all Email responds goes with the same ticket number. If someone sends an Email to support@mydomaincom, a ticket gets created and I do get a copy as well. So, instead of my logging into the OSticket system and respond online to the ticket, I like to be able to respond to the client directly using the Email ticket that was sent to me. I hope I am not confusing you.
Thanks
Alex
