What are the main namespaces in the Zimbra SOAP API and their purposes?

The Zimbra SOAP API includes namespaces like `zimbraAccount`, `zimbraAdmin`, and `zimbraMail`. `zimbraAdmin` is used for mail server management (requires admin privileges), `zimbraAccount` handles user-related operations, and `zimbraMail` deals with mail-related tasks. For more details, refer to the Zimbra SOAP API Development Guide.
