    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_WRITE);

    Message[] messages = null;
    boolean isMailFound = false;
    Message confirmationMAil = null;

    // Search for mail MAX 10 runs

在调用Session类之前尝试添加它：

System.setProperty("javax.net.ssl.trustStore", path to your cacerts file in your Java folder, inside your hard disk);
        System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
        Properties prop = new Properties();
        prop.setProperty("mail.pop3.starttls.enable", "false");
        prop.setProperty("mail.pop3.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        prop.setProperty("mail.pop3.socketFactory.fallback", "false");
        prop.setProperty("mail.pop3.port", port);
        prop.setProperty("mail.pop3.socketFactory.port", port);
        prop.setProperty("mail.imap.ssl.trust", "*");
        MailSSLSocketFactory sf = new MailSSLSocketFactory();
        sf.setTrustAllHosts(true);
        prop.put("mail.smtp.ssl.socketFactory", sf);
