I want to force people to use the web portal to submit a new ticket, because I want them to fill out the help topic and other mandatory information themselves.. However, I do want them to be able to reply to the automated emails that get sent out when we post comments on their tickets, and I want those replies to tag themselves to the ticket. Is there a way (without modifications to source) to auto-reject emails that are not tagged to an existing ticket, so a new one doesn't get created?Thanks in advance for any assistance.
