+### Mail Transfer Agent (MTA)
+
+The platform includes a robust Mail Transfer Agent (MTA) for enterprise-grade email handling with complete control over the email delivery process:

+    end
+```
+
+The MTA service provides:
+- Complete SMTP server for receiving emails
+- DKIM signing and verification
+- SPF and DMARC support
+- DNS record management
+- Retry logic with queue processing
+- TLS encryption
+
+Here's how to use the MTA service:
+
+```ts
+import { MtaService, Email } from '@serve.zone/platformservice';
+
+async function useMtaService() {
+  // Initialize MTA service
+  const mtaService = new MtaService(platformService);
+  await mtaService.start();
+  
+  // Send an email
+  const email = new Email({
+    from: 'sender@yourdomain.com',
+    to: 'recipient@example.com',
+    subject: 'Hello World',
+    text: 'This is a test email',
+    html: '<p>This is a <b>test</b> email</p>',
+    attachments: [] // Optional attachments
+  });
+  
+  const emailId = await mtaService.send(email);
+  console.log(`Email queued with ID: ${emailId}`);
+  
+  // Check email status
+  const status = mtaService.getEmailStatus(emailId);
+  console.log(`Email status: ${status.status}`);
+  
+  // Set up API for external access
+  const apiManager = new ApiManager(mtaService);
+  await apiManager.start(3000);
+  console.log('MTA API running on port 3000');
+}
+
+useMtaService();
+```
+
+The MTA provides key advantages for applications requiring:
+- High-volume email sending
+- Compliance with email authentication standards
+- Detailed delivery tracking
+- Custom email handling logic
+- Multi-domain email management
+- Complete control over email infrastructure
