关于apache common-mail发邮件，部分邮箱无法接收问题

最近用common-mail做邮件发送，但部分邮箱总是无法接收，一直找不到原因，请高手指点一下，谢谢！

代码：

//yahoo

//String   hostName   =   "smtp.qq.com ";

//String   from   =   "funcreal@qq.com ";

//String   username= " ";

//String   password= " ";

String   to   =   "funcreal@yahoo.com.cn ";

email.setHostName(hostName);

email.setFrom(from);

email.setAuthentication(username,password);

email.addTo(to);

email.setSubject( "Test   email   with   inline   image ");

email.setMsg( "test   msg ");

email.send();

现象：有些邮箱总是无法收到邮件。有人说是被拒绝了。但是用同样的帐户，用outlook或者foxmail就可以发过去。用代码发和用outlook发有什么不同呢？难道用代码发送，会在邮件头增加某种转发ip地址等信息？这个也说不太通。我在foxmail中查看邮件原始信息(这是个可以接收代码发送的邮件的信箱)，代码发的和outlook发的是基本相同的，只是头信息中部分信息不同(于是我在代码中加入了outlook的头信息，让它看起来和outlook相同)。请看示例：

开头少了个声明：SimpleEmail email = new SimpleEmail();
