CloudMailin
Inbound email-to-HTTP processing with documented post formats and a separate outbound transactional service. Choose the right authentication and payload for each direction.
Start with the first guide, then choose a sending, receiving, or feedback task. Each walkthrough identifies permissions, operational checks, and the boundary between the service and MailKite. Refer to the official CloudMailin documentation for current platform requirements.
