DNS Health Check
Run a real public-infrastructure diagnostic with prioritized findings and technical evidence.
What is checked
DomainPulse resolves relevant records, validates configuration and—where applicable—safely connects to mail endpoints without sending email.
Common problems
Missing records, invalid syntax, lookup loops, connection timeouts, weak policies, hostname mismatch and certificates approaching expiry.
FAQ
Is this intrusive?
No. Scans use normal public DNS and SMTP handshake operations. No message DATA is sent.
Why monitor?
Monitoring detects changes and recovery after the point-in-time check.
