Troubleshooting
Common Issues
| Problem | Solution |
|---|---|
| Authentication Errors | Verify that the SMTP credentials are correct and the server supports the authentication method |
| Connection Timeout | Check SMTP host and port settings, ensure firewall allows SMTP connections |
| SSL/TLS Issues | Verify SSL/TLS settings match your SMTP server requirements |
| Send Email Fails | Verify recipient email addresses and ensure the SMTP server allows sending |
| Rate Limiting | Implement appropriate delays between email sends to avoid hitting rate limits |
| Port Blocking | Ensure the SMTP port (usually 587, 465, or 25) is not blocked by firewall |
Debugging
- Check SMTP server logs for detailed error messages
- Verify SMTP credentials and server settings
- Test SMTP connection using email client or command line tools
- Monitor SMTP server quota and rate limits
- Validate email addresses and message content
- Check network connectivity and firewall settings
- Review SMTP server documentation for specific error codes
- Ensure proper SSL/TLS configuration for secure connections
