The EmailHeader constructor takes three boolean arguments: triggerAutoResponseEmail, triggerOtherEmail, and triggerUserEmail.

triggerAutoResponseEmail - Indicates whether to trigger auto-response rules (true) or not (false), for leads and cases. In the Salesforce user interface, this email can be automatically triggered by a number of events, for example resetting a user password.

triggerOtherEmail - Indicates whether to trigger email outside the organization (true) or not (false). In the Salesforce user interface, this email can be automatically triggered by creating, editing, or deleting a contact for a case.

triggerUserEmail - Indicates whether to trigger email that is sent to users in the organization (true) or not (false). In the Salesforce user interface, this email can be automatically triggered by a number of events; resetting a password, creating a new user, adding comments to a case, or creating or modifying a task.
