SMTP Monitoring
Outbound relay validation.Zero delivery gaps.
Secure your outbound mail flow. Validate the reachability and handshake integrity of your SMTP servers to detect delivery failures before they disrupt business communication.
Outbound Service Validation
The SMTP Monitor verifies that your mail gateway is reachable and responsive. It is a critical control instrument for identifying outages in your outbound infrastructure at an early stage.
- Handshake Integrity: We connect to your SMTP server and validate whether it responds correctly to the protocol challenge within the defined timeout.
- Proactive Error Detection: Identify hanging mail queues or gateway failures before clients or automated systems lose the ability to send emails.
- Sovereign Reachability: Ensure your mail backbone remains accessible to authorized clients across your entire portfolio at all times.
Port & Encryption Auditing
Support for all common SMTP standards. Validate the correct configuration of your ports and the integrity of the utilized encryption layers.
- Flexible Port Monitoring: Monitor standard ports (25) as well as dedicated submission ports (587, 465) matching your individual setup.
- TLS/SSL Validation: Verify that encrypted connections (STARTTLS/SSL) are negotiated correctly to guarantee data security in transit.
- Status Orchestration: Use Maintenance mode during scheduled server updates to preserve telemetry data while temporarily suppressing alerts.
Global Relay Accessibility
Verify your mail server's reachability from our global monitoring network to identify regional routing issues or firewall misconfigurations.
- Regional Access Checks: Use Allowed Check Countries to limit monitoring exactly to the regions where your infrastructure or your customers operate.
- Firewall Verification: Ensure that your IP whitelists and security policies correctly permit access from our monitoring nodes at all times.
- Diagnostic Feedback: Receive precise logs pinpointing whether a check failed due to timeouts, connection refusals, or TLS handshake errors.
