Question

我正在尝试使用java中的godaddy帐户发送电子邮件。以下是我的代码。

Properties props = System.getProperties();
props.put("mail.transport.protocol","smtp" );
props.put("mail.smtp.starttls.enable","true" );
props.put("mail.smtp.ssl.enable", "false");
props.put("mail.smtp.host","smtpout.secureserver.net");

props.put("mail.smtp.auth","true");
props.put("mail.smtp.port","465");
props.put("mail.debug","true");
props.put("mail.smtp.socketFactory.port","465");
props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback","false");


 Authenticator auth = new SMTPAuthenticator();
 Session session=Session.getInstance(props,auth);
 session.setDebug(true);

 // -- Create a new message --
 Transport transport=session.getTransport();

 Message msg = new MimeMessage(session);
 // -- Set the FROM and TO fields --
 msg.setFrom(new InternetAddress(""email@domain.com));
 msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse("email@domain.com", false));
 msg.setSubject("subject");
 msg.setText("Message");

 transport.connect();
 Transport.send(msg);
 transport.close();

执行时我收到以下异常。

com.sun.mail.util.MailConnectException：无法连接到主机，端口：smtpout.secureserver.net，465;超时-1; 嵌套异常是： java.net.UnknownHostException：smtpout.secureserver.net

PS：当我使用gmail帐户进行身份验证时，其工作正常并且电子邮件已成功发送。当我使用godaddy帐户时，异常抛出。

请指导我如何解决这个问题...

提前致谢...

Answer 1

我在SpringBoot中的配置（将domainname.com替换为您的域名）

spring:
  mail:
    host: smtpout.secureserver.net
    port: 465
    username: info@domainname.com
    password: password
    protocol: smtp
    properties.mail.smtp:
      auth: true
      ssl.enable: true
      ssl.trust: "*"

我还必须在发送邮件之前添加mimeMessageHelper.setFrom("info@domainname.com");（否则它将使用我的系统名称并给出了错误），并且此设置有效。

Answer 2

JavaMail SSL with no Authentication trust certificate regardless

    MailSSLSocketFactory socketFactory = new MailSSLSocketFactory();
    socketFactory.setTrustAllHosts(true);

需要javax.mail 1.5.2及更高版本

这是对我来说绝对有效的完整方法（我在邮件中也使用了附件）：

private void sendUsingSmtp(MailDetail mailDetail) {
        Properties props = new Properties();
        props.put("mail.host", "smtpout.secureserver.net");
        props.put("mail.port", "465");
        props.put("mail.username", "info@domainName.com");
        props.put("mail.password", “password”);
        props.put("mail.protocol", "smtp");

        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.ssl.enable", "true");
        props.put("mail.smtp.ssl.trust", "*");


        Session session = Session.getInstance(props, new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("info@domainName”, “password");
            }
        });
        MimeMessage msg = new MimeMessage(session);
        try {
            msg.setFrom(new InternetAddress("info@domainName.com", false);
            msg.setRecipients(MimeMessage.RecipientType.TO, InternetAddress.parse(“targetEmail@gmail.com"));
            msg.setSubject("Test Subject.");
            msg.setContent("Test Content.", "text/html");
            msg.setSentDate(new Date());

            MimeBodyPart messageBodyPart = new MimeBodyPart();
            messageBodyPart.setContent("Test Content.", "text/html");

            Multipart multipart = new MimeMultipart();
            multipart.addBodyPart(messageBodyPart);
            MimeBodyPart attachPart = new MimeBodyPart();

            attachPart.attachFile("/var/tmp/abc.txt");
            multipart.addBodyPart(attachPart);
            msg.setContent(multipart);
            Transport.send(msg);
        } catch (MessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
