问题描述

我想用java发送电子邮件无需验证。
有人可以帮我吗？

I would like to send email without authentication using java. Can someone help me?

通过认证，我做如下：

    public void sendEmail() throws EmailException{
    SimpleEmail email = new SimpleEmail();
    email.setHostName("smtp.gmail.com");
    email.setSmtpPort(465);
    email.addTo("[e-mail]", "XXXX");
    email.setFrom("[e-mail]","XXXXX");
    email.setSubject("testando . . .");
    email.setMsg("testando 1");
    email.setSSL(true);
    email.setAuthentication("[e-mail]", "XXXXX");

推荐答案

如果它只是用于测试目的，您可以尝试的 Papercute 。虽然它的运行，剪纸会自动选择发送到任何IP地址的标准SMTP端口（25）的电子邮件。你只需从你的应用程序中发送邮件，并切换到剪纸对其进行审查。

If it is only for testing purposes, you may try Papercute. While it’s running, Papercut automatically picks up e-mail sent to the standard SMTP port (25) on any IP address. You just send mail from your application and switch to Papercut to review it.

import java.util.Date;
import java.util.Properties;

import javax.mail.Message.RecipientType;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SendMail {

    public static void main(String[] args) throws Exception {
        Properties props = new Properties();
        props.put("mail.smtp.host", "127.0.0.1");
        props.put("mail.smtp.port", "25");
        props.put("mail.debug", "true");
        Session session = Session.getDefaultInstance(props);
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[e-mail]"));
        message.setRecipient(RecipientType.TO, new InternetAddress("[e-mail]"));
        message.setSubject("Notification");
        message.setText("Successful!", "UTF-8"); // as "text/plain"
        message.setSentDate(new Date());
        Transport.send(message);
    }

}
