Javamail在解析附件是抛出Missing start boundary异常

Ben.Sin

在做javamail通过pop3解析邮件的时候，在解析邮件包含附件的时候，在测试服务器上出现了以下异常

但是这个在本机并没有这样的异常出现。网上查了不少帖子，真正能解决这个问题不多。
 
不过有个帖子给了我点提示

后来部署到另外一台测试机器上发现能正常解析，于是停掉了原来测试机的杀毒软件，就能正常解析出来了
 
不过也在解析的时候首先判断了message是否继承与Part接口的
 
部分节选代码如下
try {if (msg instanceof Part){Part part = (Part) msg;if (part.isMimeType("multipart/*")) {Multipart mp = (Multipart) part.getContent();System.out.println(mp);int count = mp.getCount();for (int i = 0; i < count; i++) {Part p = mp.getBodyPart(i);//某些处理}mp = null;}}} catch (MessagingException e) {...省略
