- Developed Nodemailer transport adapter for SMTP over WebSocket in `transport.ts`, including methods for sending mail and verifying transport configuration.
- Defined type definitions for the SMTP over WebSocket protocol in `types.ts`, including message types, connection states, and client configuration options.
