Follow the below step-by-step guide if you need to import only parts of an email configuration into your system and override the existing ones with them.
This could be the case when you need to check another Jira instance's configuration or use templates, field rules etc. of another environment.
In this tutorial, we will import the mail handler, mail account and templates into an already existing configuration (which could be useful in case of a service management support channel where you need to see another test environment's settings).
