Customer created a ticket through email. Ticket got created,From second email ticket is not creating

[Madhu Reddy]

When a customer sends a mail, ticket got created and Customer was added to Users, Jira Customers.

When a customer sends a second mail, He was unable to create tickets. His mail was not even read by Jira.

Urgent Issue.

I don't want Jira to create user for customers when he sends a mail.

In that case, you should unmark the create user checkbox and provide the default reporter.

And the user which you are providing for default reporter he/she should have the create issue permission for that specific project then only the issue will create.

Thanks @Yogesh Mude 

In that Scenario my customer is not getting any kind of reply mail.

Customer must get a reply mail saying that " Your ticket was Created.. And Issue Key number must be send to him "

So that from there he can Signup to Customer Portal.
