Wildfly javamail 和 mailsession 注入向 SMTP 服务器发送 HELO 命令失败

Question

所以我需要一些说明。我正在尝试使用 google SMTP 服务器发送电子邮件，使用我的 google 应用程序帐户（免费的东西，而不是中继）。我正在使用 wildfly 10 容器（和 JSF），所以我的项目中没有 javamail jar（正确吗？）。所以在我的无状态 EJB 中，我进行了资源注入：

@Resource(name = "mail")
private javax.mail.Session mailSession;

在我的 standalone.xml:

<subsystem xmlns="urn:jboss:domain:mail:2.0">
        <mail-session name="mail" jndi-name="java:/mail"/>
</subsystem>

所以我假设我不必在独立版本中定义端口、用户名和密码，如果我只是添加这样的属性：

Properties props = System.getProperties();
    String host = "smtp.gmail.com";
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.host", host);
    props.put("mail.smtp.user", "XXXX@gmail.com");
    props.put("mail.smtp.password", "XXXX");
    props.put("mail.smtp.port", "465");
    props.put("mail.smtp.ssl.enable", "true");
    props.put("mail.smtp.auth", "true");

    mailSession = Session.getDefaultInstance(props, 
            new javax.mail.Authenticator(){
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(
                        "XXXX@gmail.com", "XXXX");// Specify the Username and the PassWord
                }
        });

这是否正确，或者是否还需要在 standalone.xml 中定义？

所以我得到错误： javax.mail.MessagingException: 向 SMTP 服务器发送 HELO 命令失败

感谢任何有关如何实现此工作的帮助！

完整代码如下：

            String emailString =  managedList.get(i);
            if(emailString.isEmpty() == true){
                System.out.println("emailString is empty");
            }
            else{
            to[i] = new InternetAddress(java.net.IDN.toASCII(emailString));
            }
        }

        m.setRecipients(Message.RecipientType.TO, to);
        m.setSubject("Wildfly 10 - Checkbox test");
        m.setSentDate(new java.util.Date());
        BodyPart messageBodyPart = new MimeBodyPart();

        // Fill the message
        messageBodyPart.setText("testing application managed javamail props");

        // Create a multipart message
        Multipart multipart = new MimeMultipart();

        // Set text message part
        multipart.addBodyPart(messageBodyPart);
        m.setContent(multipart);
        Transport transport = mailSession.getTransport("smtp");
        transport.connect(host, "XXXX@gmail.com", "XXXX");
        transport.send(m);
        transport.close();
        System.out.println("Mail sent!");


    } catch (javax.mail.MessagingException e) {
            e.printStackTrace();
    }
}

}

这也是堆栈跟踪的一部分，会不会是 geronimo 的问题？我可以改用 sun 吗？如果可以，我该怎么做？

好吧，我认为我的道具中缺少 SSL 套接字工厂，但我现在切换到使用 TLS 并且它有效！这是一个 link：http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/ 真的，我只是把它复杂化了。
