Create new ticket when user "replies" to a ticket they are not a requestor on

Using RT 4.0.17

Occasionally we have an instance where the ticket requestor forwards a
reply from us to a third party to ask them to comment on something in
the ticket. The third party then replies to the email including our
address and leaving the subject intact so it has the RT ticket id string
in it.
We don’t have permissions enabled for the Everyone group to be able to
reply to tickets so the email from the third party is bounced back with
the appropriate error telling them they don’t have permission to add to
the ticket.
Rather than this we would like RT to create a new ticket which we can
then link/merge with the existing ticket.

A search has not revealed whether this is possible and, if so, how to
make this the default behaviour.

Has anybody configured RT to work this way?

Regards

Does ‘Everyone’ have CreateTicket?
If so, you might be able to write some code based on this extension to
do what you want:

This does require a recent RT4 release to provide the hooks you would
use.
