Troubleshooting

Common Issues

Authentication Failed

Ensure you're using your actual API key (not placeholder text) for both username and password fields.

Connection Timeout

Check that your server can make outbound connections on ports 587 or 465. Some hosting providers block these ports.

SSL/TLS Issues

Try switching between TLS (port 587) and SSL (port 465) if you encounter encryption-related errors.

Testing Your Setup

Use this simple curl command to test your SMTP connection:

# Test SMTP connection
curl -v --ssl-reqd \
  --url 'smtps://smtp.fudd.link:465' \
  --user 'smtp_injection:YOUR_API_KEY' \
  --mail-from 'test@yourdomain.com' \
  --mail-rcpt 'recipient@example.com' \
  --upload-file - <<< $'Subject: Test\n\nThis is a test message.'
