=====================
用的是Jmail4.3
经过测试没问题可以多发！
1.安装jmail4.3
2.找到jmail.dll（Program Files\Dimac\w3JMail4下）
3.执行Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Bin\ildasm.exe（可使用Visual Studio .Net 2003 命令提示),
格式如下：tlbimp c:\Program Files\Dimac\w3JMail4\jmail.dll /out:myJmail.dll /namespace:myJmail
就是我在Visual Studio .Net 2005命令提示下编译执行 tlbimp c:\Program Files\Dimac\w3JMail4\jmail.dll /out:myJmail.dll /namespace:myJmail
