Hello Team, I have an “issue” with Duplicates tickets in this case :

When customer send mail to a others guys and put the integration mail in copy thats create a tickets in Zammad - thats OK

But when the others Guy do a reply all, and respond to the customer, thats create a new tickets and do not implement the first one - i think because they dont have the N°tickets in the title of the mail.

Can we do something for thats ?

Thanks all
