JMAP (JSON Meta Application Protocol) is a modern, efficient, and stateful protocol for synchronizing mail, calendars, and contacts between a client and a server. It operates over HTTP and uses JSON as its data format. This makes it highly accessible and easy to implement across various platforms. JMAP is designed to handle large amounts of data and manage this efficiently, offering performance benefits over traditional mail protocols. It offers a consistent interface for different types of data, making it easier for developers to understand and use. The protocol also provides built-in support for push updates, ensuring that changes are immediately reflected on all connected devices.
A session represents the stateful interaction between the client and the server. It maintains the state of a user's actions and can be used to handle user requests more efficiently. When a client connects to the JMAP server, a new session is initiated. This session contains necessary details like account details, permissions, disk quotas, etc.
The JMAP Protocol settings section covers the configuration parameters for the JMAP server. These parameters influence various aspects of the protocol's behavior, such as request handling, data uploading, quota management, email and mailbox settings, and event processing.
OAuth, or Open Authorization, is a standard protocol that provides a method for clients to access server resources on behalf of a user. It acts as an intermediary on behalf of the end-user, providing the service with an access token that authorizes specific account information to be shared. This allows users to grant third-party applications access to their information on other services without sharing their credentials. For security reasons, it is strongly recommended to always use OAuth to
