Real-Time SMTP Monitoring
Track your mail server's uptime and performance. We open a live TCP connection, measure response latency, capture the greeting banner, and analyze TLS encryption capabilities.
Real-Time TCP Connection Diagnostics & TLS Capability Audit
Ensure your mail infrastructure is constantly available and cryptographically secure. We establish genuine, physical TCP handshakes with your mail server, capturing the 220 greeting banner and precisely measuring latency in milliseconds to detect network bottlenecks. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our backend executes EHLO commands to verify your STARTTLS capabilities and fully supports secure SSL/TLS tunneling for Port 465, providing an immediate and reliable audit of your server's ability to accept traffic without relying on cached data or simulated network responses.
