Can I Send SMTP Traffic Using My VPS?
Yes! DartNode allows unlimited outbound SMTP traffic by default on all VPS services.
📌 Important Notes
🚫 We do not impose any artificial SMTP blocks or rate limits
🛡️ However, if your VPS IP is added to a blacklist due to spam or abuse, DartNode will automatically block outbound SMTP to protect network integrity
✅ Best Practices for Sending Email
To keep your server email-friendly and avoid blocks:
🔐 Secure your server to prevent unauthorized sending
🛠️ Set up SPF, DKIM, and DMARC records for your domains
📊 Monitor your outgoing mail logs and IP reputation regularly
