代码应该是没有错的，因为它经常可以发出去，就是偶尔会报554，但是还是把代码贴出来，求大神帮忙看看，怎么解决，现在就是我常用邮箱大部分可以成功发送，偶尔出现554，新申请本来打算用作专用邮箱的结果是一封邮件也发不出去，一直554，同样的邮件内容；代码如下：

//发email-----------start
    Properties props=new Properties();
    Properties mymailprops=new Properties();
    InputStream pis=this.getClass().getClassLoader().getResourceAsStream("Jmail.properties");
    InputStream mymailpis=this.getClass().getClassLoader().getResourceAsStream("mymail.properties");
    props.load(pis);
    mymailprops.load(mymailpis);
    Authenticator authenticator=new Authenticator() {
        @Override
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(mymailprops.getProperty("accountname"),mymailprops.getProperty("password"));
        }
    };
    Session session=Session.getInstance(props,authenticator);
    MimeMessage msg=new MimeMessage(session);
    try {
        msg.setFrom(new InternetAddress(mymailprops.getProperty("fromAddress")));
    msg.setRecipients(RecipientType.TO, form.getEmail());
    msg.setRecipients(RecipientType.CC,mymailprops.getProperty("fromAddress"));
    msg.setSubject("dmandp");
    msg.setContent("欢迎加入dmandp,你的验证码为["+codes+"],请尽快完成验证.若非本人操作,请忽略此邮件.","text/html;charset=utf-8");
    Transport.send(msg);
    //发email-------------end

百度跟网易的解释是邮件有垃圾内容，但是如果这样没道理大部分情况下可以，偶尔出错，而且，有的邮箱可以有的邮箱不可以
