E-mail Notification issue in genkins

[krishna prasad]

Dear Group Members,

We have jenkins and the issue is E-mail Notification is not working for us.  We are getting below error while I click on "Test" button. Kindly help me to resolve the issue.

javax.mail.MessagingException: Could not connect to SMTP host: ourdomain.net, port: 465;
  nested exception is:
	javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
	at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1934)
	at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:638)

I have installed on iredmail on different server on locally and emails are working fine with SSL. Jenkins is installed on different server. I have configured the smtp settings of my local server in jenkins. Kindly help me to resolve this.

Note: 1. I am able to telnet to port 465 from jenkins server to mailserver

         2. I have configured the SMTP with ssl on thunderbird and able to send the mail with ssl fine. But from jenkins smtp not working.

         3. If I configure the gmail setting genkins notification working fine. 

         4. We have installed certbot SSl for our email server.

Thanks and Regards,

It is likely that your trust store does not have the needed certificates.

A less likely error is that your JVM does not have the ability to negotiate the TLS connection (ciphers, version, etc.)

Test with https://wiki.apache.org/tomcat/tools/SSLTest.java using the SAME JVM as jenkins.

certificate is certbot which is freely available ssl certificate. actually mail server is working fine with ssl. But note that this we use only inside our network.

Certificate Path: /etc/letsencrypt/live/domain.net/fullchain.pem

Private Key Path: /etc/letsencrypt/live/domain.net/privkey.pem

please let me know which tls setting
