可以看到附件的,但是只是outlook不顯示,再看Content-Type: application/ms-tnef;網上一搜,原來有bug,這下知道問題所在了,是他們有的outlook有問題.看來只有他們更改了.

用Microsoft OUTLOOK + sendmail 给对方IMail的SMTP发带有多个PDF附件的邮件，
对方用Outlook express 从IMail服务器中收取这个邮件，发现邮件大小正常，但是看不到附件。
从邮件头信息来看，所有附件都变成了只有一个附件的信息，且显示为：

Content-Type: application/ms-tnef;
name="winmail.dat"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="winmail.dat"

我查找了一下关于“application/ms-tnef”这个关键信息，多数认为是MICROSOFT的BUG，在LINUX下有几个解读“winmail.dat”的方法，但是在WINDOWS下，我没有找到行之有效的方法。
