Creates the given email policy.  If the upsert query param is set to truethen, instead of performing a create, the API will switch to performing an upsert.  For an upsert request, the following fields are required:
Required Upsert Fields:

When performing an upsert, the above fields will be used to determine whether the email policy resource already exists. If the email policy already exists, a partial update will be performed; otherwise, a new email policy entity will be created.
In the response of an upsert request, if a create was performed, then a 201 response code will be returned; otherwise, if an update was performed, then a 200 will be returned.
