Dear friends,
suddenly my code stops to work. It seems a problem in the SMTP commands....
Exception in thread "main" javax.mail.MessagingException: Can't send command to SMTP host;
nested exception is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: timestamp check failed
at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:1365)
