You can try upgrade library javax.mail.jar at https://java.net/projects/javamail/pages/Home (now version is 1.5.5) and add code :

MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true); 
properties.put("mail.imap.ssl.trust", "*");
properties.put("mail.imap.ssl.socketFactory", sf);
