此代码有什么问题?我正在尝试使用hMailServer在本地主机上发送电子邮件,但无法正常工作。虽然此代码适用于Gmail SMTP服务器。.我可能认为该错误出在我的hMailServer中,但我找不到它。
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();
}
这是我得到的错误:
javax.mail.MessagingException: Could not connect to SMTP host: 127.0.0.1, port: 25;
nested exception is:
java.net.SocketException: Permission denied: connect

我正在使用hMailServer。
最佳答案
如果您使用的是Java 7,那么我将在启动应用程序时尝试将其添加为JVM参数:-Djava.net.preferIPv4Stack=true
这可能是必要的,因为Java现在正在尝试使用IPv6,因此我们需要告诉它更喜欢IPv4堆栈。
