這段代碼有什麼問題?我試圖用hMailServer在本地主機上發送電子郵件,但它不起作用。儘管此代碼正在爲Gmail的SMTP服務器。我可能會認爲錯誤是在我的hMailServer,但我不能找到它..Java連接到本地SMTP服務器
try{
String host = "127.0.0.1";
String from = "[email protected]";
String pass = "1q2w#E$R";
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true"); // added this line
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "25");
props.put("mail.smtp.auth", "true");
String[] to = {"[email protected]"}; // added this line
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
// To get the array of addresses
for(int i=0; i < to.length; i++) { // changed from a while loop
toAddress[i] = new InternetAddress(to[i]);
}
for(int i=0; i < toAddress.length; i++) { // changed from a while loop
message.addRecipient(Message.RecipientType.TO, toAddress[i]);
}
message.setSubject("sending in a group");
message.setText("Welcome to JavaMail");
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
catch (Exception e) {
e.printStackTrace();
}
這是我得到的錯誤:
javax.mail.MessagingException: Could not connect to SMTP host: 127.0.0.1, port: 25;
nested exception is:
java.net.SocketException: Permission denied: connect

我使用hMailServer ..
您是否嘗試過使用標準客戶端連接到本地SMTP服務器,例如Thunderbird? –
