Auto-reply to customer which is not registered on the system and which send email to osticket

Hello,

I am using below osTicket version:



I configured that only registered users can create tickets. So only registered users can also send emails to my default osticket email support@domain.com

If unregistered user will send email to this address support@domain.com then this message is rejected and deleted from mail box.

What I want to do is to set somehow autoresponder to these not registered users that e.g. "Your email was deleted - please register Your account if You want create tickets"

I was trying to do this by ticket filters - I found rule how to find which user is not registered but there is not possible to configure ACTION to auto-reply to this user.

Is it possible??

Thanks in advance
