Added scheduled task functionality, which allows using cron expressions to periodically read results from an API or link and send emails. Supports configuring templates for JSON response APIs to convert JSON data into text for email content.

A gateway service that converts SMTP protocol to HTTP interfaces, helping developers:

• Avoid hardcoding SMTP configurations in code
• Dynamically send emails through REST API
• Visually configure multiple SMTP providers
• Use scheduled tasks to reduce email configuration in projects

• 🚀 Configure SMTP servers and recipient emails via Web UI
• 📦 Support for GET/POST/JSON request formats
• 🔒 Token-based API access control
• 📎 Multi-file attachment support (Base64 encoding/form upload)
• 🐳 Ready-to-use Docker image
• 📊 Send record query and statistics
• 📅 Scheduled task support for requesting links and sending emails
• 📧 Email template support
