I don't use RT, and it is lightly used here.  I am just the guy that has to keep it working.  :-)

You might be able to have the MTA detect a ticket number in the subject without a corresponding X-RT-Ticket entry, and when found, mung the subject to break the recognition.  [Perhaps insert the words "refers to" between the site name and ticket number.]

Generally, this tag is to prevent mail loops, not to determine what the ticket number is.

Tell them that if they don't remove the number, then the response is automatically routed to the old closed ticket where no action will occur.  Sometimes users are hard to train.  :-)

If you want the message to create a new ticket, then you need to change the detection of a ticket number in the subject to only occur if you also have the X tag.  Which will break regular replies to the ticket when they are forwarded instead of replied to.  Another policy is to route any reply to a ticket that is more than 30 days (or whatever) past the date of ticket closure goes to a special queue as a new ticket, where it can be manually determined if it should reactivate the closed ticket or make a new one.  Again, that requires modifying RT code.
