Once the Mail servers are configured, as an administrator you can configure Form Mail ID's which can then be used in a form. Form Mail IDs are reusable and can be used across several forms, making them a convenient for defining the behaviour of several forms.
Once, the Form Mail ID has been configured, the administrator can edit and change all the fields of the Configured Form Mail except the Form Mail ID which is immutable.
Form Mail ID's can also be used to create a Form Mail Inbox in Confluence which can be accessed via the administration page to view received responses to a form.
