服务器上的javamail问题但在本地工作

Question

我一直在努力从我的ubuntu服务器发送邮件。奇怪的是，它在我的mac上的本地tomcat实例上运行得非常好。

以下是我的实现:

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

    Session session = Session.getInstance(props,
              new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("[e-mail]", "mypassword");
                }
    });
    session.setDebug(true);
    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[e-mail]","Team"));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[e-mail]"));
        message.setSubject(title);
        message.setContent(htmlContent,"text/html");

        Transport.send(message);

    } catch (MessagingException e) {
        logger.error("Could not send email, MessagingException : "+e.getMessage());
        throw new CouldNotSendEmailException();
    } catch (UnsupportedEncodingException e) {
        logger.error("Could not send email, UnsupportedEncodingException : "+e.getMessage());
        throw new CouldNotSendEmailException();
    }

让我恼火的是，javamail的输出日志在我的服务器和本地是一样的，而且没有错误:

到目前为止我所做的一切

检查我的垃圾邮件（比如一千次，以防万一...

尝试了其他端口，如465和25-

使用iptable打开587端口

iptables -A 输出 -p tcp --dport 587 -j 接受

iptables-A INPUT-p tcp-dport 587-j ACCEPT

我现在开始感到有点绝望，如果有人有主意，那将不胜感激。

看起来问题出在您的邮件服务器中。它接受消息，但随后将其排队，从不传递或丢弃。您需要查看邮件服务器的日志和配置。

顺便说一句，有一个更新版本的JavaMail可用。
