What it does
RMail provides encrypted email, secure file sharing and delivery-record features. The product supports mailbox integrations, gateway deployment and APIs for organizational workflows.
RMail combines protected delivery with a record of the exchange. Its Registered Receipt is presented as a way to document delivery and message handling, useful when an organization needs more than a read notification. Legal weight and admissibility are separate questions from the feature itself. The official page also lists email-client integration, gateway and API routes. Choose the deployment around who should apply protection: an individual sender or a centrally administered mail flow.
