When  a mail comes into our support mail box, Tickets are created in Jira.

We are looking for automation, so the "cc"ed person in mail should automatically created as customers.

Hi @Nicolas Grossi 

Let me be more descriptive.

When customers send mail to our support mail box. customers who are in "CC" should automatically added as customers. Is there a way to do that? so that I can make them as "request participants". So, they will get to know about every notification. Now, what happens is that only the reporter of the issue is getting notified of everything happening in Jira. 

We don't want to add customers manually because we have lot of customers working .
