javax.mail.MessagingException無法連接到SMTP主機端口：25響應-1

我得到的響應代碼爲-1，我不確定這是什麼解決方法。辦公室有一個防火牆設置，不能被禁用以及防病毒運行。因爲java代碼是從辦公室運行的，所以我怎麼讓這段代碼通過電子郵件發送測試報告。javax.mail.MessagingException無法連接到SMTP主機端口：25響應-1

代碼發送電子郵件：

Properties props = new Properties(); 
props.put("mail.smtp.host", SMTP_HOST_NAME); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.debug", "true"); 
props.put("mail.smtp.port", SMTP_PORT); 
Session session = Session.getInstance(props, new javax.mail.Authenticator() { 
    protected javax.mail.PasswordAuthentication getPasswordAuthentication() { 
     return new javax.mail.PasswordAuthentication("myusername","mypassword"); 
    } 
});

您可以通過從命令提示符輸入「telnet xxx.com 25」連接到同一個郵件服務器嗎？ – mthmulders

嗨，由於管理員權限被禁用，我無法做到這一點。 – JaiK

在這種情況下，您是否可以連接到給定郵件服務器的端口25，確保您的雙重，三重確定？ – mthmulders

從Java Mail API FAQ：

你應該叫trans.sendMessage(msg, addrs)發送消息。如上所述，send方法是一種靜態便利方法，它獲取自己的Transport對象並創建自己的連接以用於發送;它不使用與調用它的任何Transport對象相關的連接。

總之，不要致電Transport.send(...)，請致電Transport.sendMessage(...)來代替。
