Issue clone only cloning when issue is created manually not from incoming mail in Jira

[Anunna Mandal]

I have added a listener to clone issue with a script added the event - Issue creation for execution of the listener in one of our Jira project.
so that whenever new issue is created through mail in the project the listener should execute the clone issue script.But the listener is only creating clone issue when the issue is created manually in that project and not cloning the issue which are created from incoming mail in Jira. and also the cloned issues are not getting created with all the added custom fields and system fields as in the original issue Issue even though added in the issue clone script.

Is there any other event need to be used for the issue clone when the jira issue is created through incoming mail
