Answer 1

If It is the problem persisted in Java 6 then the solution is simple.It is just simple as Java 7 was released.Install java 7 in machine.java 7 have the certificates file having the capability of ignoring certificate authentication.

copy the "cacerts" file from following java 7 directory

C:\Program Files\Java\jdk1.7.0_79\jre\lib\security

and paste it in

C:\Program Files\Java\jdk1.6.0\jre\lib\security

now the certificate authentication problem will be resolved.

Answer 2

I was the same issue.

MailSSLSocketFactory socketFactory = new MailSSLSocketFactory(); socketFactory.setTrustedHosts(new String[] { "my-server"});

socketFactory.setTrustAllHosts(true); props.put("mail.smtps.socketFactory", socketFactory);

it's works!!

Answer 3

use prop.put("mail.imaps.ssl.trust", "*"); since you are using imaps store.

and for smtp you can try : prop.put("mail.smtp.ssl.trust", "*"); .

Answer 4

     Properties propsSSL = new Properties();
     propsSSL.put("mail.transport.protocol", "smtps");
     propsSSL.put("mail.smtps.host", "hostname");
     propsSSL.put("mail.smtps.auth", "true");
     propsSSL.put("mail.smtps.ssl.checkserveridentity", "false");
     propsSSL.put("mail.smtps.ssl.trust", "*");

Above changes will fix javax.mail.MessagingException: Could not connect to SMTP host: hostname, port: 465; for the nested exception

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Path does not chain with any of the trust anchors
