Brightspace adds authentication mechanisms (SPF includes) that route institutional email through D2L's infrastructure. In the .edu space, these includes often coexist with Microsoft 365 delegations, creating a layered authentication picture where institutional mail can originate from multiple service providers. Understanding this multi-provider setup is important when validating whether email from an educational domain is legitimate, since Brightspace-authenticated mail may come from D2L servers rather than the institution's own infrastructure.
