从Windows 8无法发送邮件

Question

我们编写了通过Gmail SMTP服务器发送邮件的代码。它在Windows 7机器上运行得很好，但在Windows 8机器上却没有工作。

Configurations

Outgoing Mail (SMTP) Server
requires TLS or SSL: smtp.gmail.com (use authentication)
Use Authentication: Yes
Port for TLS/STARTTLS: 587
Port for SSL: 465

码

final String username = "aaa@gmail.com";
        final String password = "aaa";

        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");

        Session session = Session.getInstance(props,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(username, password);
                    }
                });

        try {

            String itemNames = getItemNames(itemSet);
            String purchaseNote = "";

            if (delAddress == null) {
                purchaseNote = "You can collect the items in our store by giveing the tracking number with in 10 days.";
            } else {
                purchaseNote = "N/A";
            }

            Message message = new MimeMessage(session);
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse("arjun@gmail.com"));
            message.setSubject("SuperDeal Purchase Detail");
            message.setText("Dear " + customer.getFullName() + "\n\n" + "Purchase Items: " + itemNames + "\n" + "Total Cost: " + totalCost + "\n" + "Tracking No: " + trackingNumber + "\n" + "Purchase Note: " + purchaseNote + "\n\n" + "Note: If you have any queries please call to our hot line 0112345647 any time.");

            Transport.send(message);
        } catch (MessagingException exception) {
            LOGGER.error(exception.getMessage(), exception);
        }

请告诉我为什么这在Windows7中很好，而在Windows8中不起作用。

Answer 1

您没有在邮件中设置From地址，而且JavaMail无法确定要使用的地址。后者的出现通常是因为JDK无法确定本地主机的主机名，可能是因为它使用DHCP获取IP地址，也可能是因为名称服务在本地计算机上配置不正确。

无论如何，简单的修复方法是在您的邮件上设置一个From地址，无论如何，您都应该这样做。
