从java smtpapi发送邮件
我正在尝试使用 Java 程序和 JavaMailApi 发送邮件。我已经编写了这个程序并有一个本地 SMTP 服务器。这不是问题。我不知道在主机地址中应该输入什么。请查看我的代码并让我知道我应该做什么?
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
// Send a simple, single part, text/plain e-mail
public class TestEmail {
public static void main(String[] args) {
// SUBSTITUTE YOUR EMAIL ADDRESSES HERE!!!
String to = "[email protected]";
String from = "[email protected]";
// SUBSTITUTE YOUR ISP'S MAIL SERVER HERE!!!
String host = "smtp.yourisp.net";
// Create properties, get Session
Properties props = new Properties();
// If using static Transport.send(),
// need to specify which host to send it to
props.put("mail.smtp.host", host);
// To see what is going on behind the scene
props.put("mail.debug", "true");
Session session = Session.getInstance(props);
try {
// Instantiatee a message
Message msg = new MimeMessage(session);
//Set message attributes
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject("Test E-Mail through Java");
msg.setSentDate(new Date());
// Set message content
msg.setText("This is a test of sending a " +
"plain text e-mail through Java.\n" +
"Here is line 2.");
//Send the message
Transport.send(msg);
}
catch (MessagingException mex) {
// Prints all nested (chained) exceptions as well
mex.printStackTrace();
}
}
}//End of class
I am trying to send a mail using a Java program and JavaMailApi. I have written this program and having a local SMTPServer. This is not a problem. I don't know what to put in host address. Please have a look at my code and let me know what should I do?

主机地址是您的 SMTP 服务器的 IP 地址或域名。
Host address is the your SMTP server's IP address or domain name.
Host是
gmail的,
应该可以用。
但请记住,要使这些邮件 api 正常工作,您应该从您的 Gmail 帐户启用 pop3 和 smtp。并且无需额外设置(例如 2 路安全登录可防止任何人使用来自其他 api 的 smtp/pop3)。
Host is
for gmail
it should work .
But remember for these mailing api to work, you should enable pop3 and smtp from your gmail account. And no extra settings ( like 2-way security login prevents any one to use smtp/pop3 from other apis ).
