osTicket v1.10 (stable) and Maintenance Release v1.9.15 are now available! Go get it now
Anybody can reply to a ticket using the same email subject
Since 1.7.1 (or 1.7.2) anybody (staff, customers, users, ...) can reply to an existing ticket. Only the email subject have to be the same as the subject of an existing ticket. This is very ugly leading to some confusing for our staff as well as our customers.
We want back the behavior before 1.7.1. If we get an email with the same subject but from a different email address, a new ticket should be crated. How do to that? I have looked in admin panel for a setting, but I did not find one. So I guess I have to change source code?
