I have setup SMTP in our Ignition 8.0.6 with default configurations.

SMTP host:----  
Port: 25  
STARTTLS  
TLS/SSL: as default.  
But it is giving error while running the test mail like javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find find valid certification path to requested target  
can anyone please explain me why the error is coming and how to resolve it.
