用於SMTP認證的javaMail API加密SSL加密

我想通過smtp服務器發送電子郵件。所以我使用javaMail API。我的屬性是：用於SMTP認證的javaMail API加密SSL加密

Properties emailProperties = new Properties(); 
emailProperties.setProperty("mail.host", emailHost); 
emailProperties.setProperty("mail.transport.protocol", "smtps"); 
emailProperties.put("mail.smtps.auth", "true"); 
emailProperties.setProperty("mail.smtps.ssl.enable", "true"); 
emailProperties.setProperty("mail.smtps.ssl.required", "true"); 
emailProperties.put("mail.smtps.port", emailPort); 
emailProperties.put("mail.smtps.socketFactory.port", "465"); 
emailProperties.put("mail.smtps.socketFactory.class","javax.net.ssl.SSLSocketFactory"); 
emailProperties.put("mail.smtps.socketFactory.fallback", "false"); 
emailProperties.setProperty("mail.smtps.quitwait", "false"); 
Log.i("GMail", "Mail server properties set."); 
mailSession = Session.getInstance(emailProperties, this); 
mailSession.setDebug(true);

當我檢查日誌，我得到：

我不明白的是，我設置mail.transport.protocol到smtps但是當你讀了日誌，有你可以看到AUTH LOGIN PLAIN和PROVIDER你可以看到smtp。那裏缺少什麼？我想強制SSL加密還是我的密碼，用戶名和文本已經發送加密了？
