ASP.NET用Jmail实现邮件群发

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
