这呢？好吧你们都是大神！！
请教 这个能解么？
这段代码又该怎么称呼呢？

Answer 4

这个才是嘛大致上最上面是信头，包括邮件从哪到哪，谁发出的，寄给谁，ip，服务器等等
然后是plan text的正文。因为email被设计成兼容早期的字符的客户端
然后是html的正文
然后是附件，包括嵌入在html正文中的图片和其它文件。
你用base64解码后按照文件名写成文件就得到了。如果你要解析，可以使用现成的mime解析程序，比如http://www.codeproject.com/Articles/11882/Advanced-MIME-Parser-Creator-Editorhttp://www.codeproject.com/Articles/19777/MIME-Compliant-Parserhttp://www.codeproject.com/Articles/5759/MIME-Message-Composer-Analyser
