Huge SPAM ticket chain!

Hello,

Just witnessed a huge spam ticket opening chain, some of them going to-fro same conversations.

Someone is sending spam to open (non-client) only depts of many hosts with our sales email in reply-to and same for them, this is creating a huge pile of tickets and bounces.

Do we have a way to limit how frequently an unregistered email can open tickets? It seems this is the need of the hour.

I don't think there is such a rate limiter built-in.   A ticketopen hook might work to then add the email address to the block list. This would need to have a tracking mechanism to determine how fast they are opening tickets and cron hook to then unblock after x amount of time. 

Is the tickets being opened via email or the client area ?  If via email, on your side make sure your SPF record is correct and  set to reject non-listed sources via the "-all" instead of "~all" which is a soft fail.  On the other side, they would of course need to be checking SPF but most spam systems do that.    If via the client area, a clientarea hook could do tracking via $_SESSION and block via like a redirect or a header 403 maybe.
