SMTP with TLSv1.2 exchange mail getting failed
I am trying to configure SMTP server with TLS 1.2 v, but I am getting error as SSL Certificate error occurred while connecting to the mail server. The server may have an expired or invalid SSL Certificate, may be misconfigured, or an attacker may be trying to intercept the connection. If you want to connect anyway, use the Allow Invalid Certificate option. javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.cerpath.SunCertPathBuilderException:unable to find valid certification path to request target.
certificate is already added in YF java cacerts, In certificate we have multiple Subject Alternative name as for exchange we are pointing to his LBs
I already checked below community links and verified steps but no luck, please guide if I am missing any steps
