ASP.NET用Jmail实现邮件群发

1.安装jmail4.3

2.找到jmail.dll（ProgramFiles/Dimac/w3JMail4下）

3.执行ProgramFiles/MicrosoftVisualStudio.NET/FrameworkSDK/Bin/ildasm.exe（可使用VisualStudio.Net2003命令提示),

格式如下：tlbimpc:/ProgramFiles/Dimac/w3JMail4/jmail.dll/out:myJmail.dll/namespace:myJmail

就是我在VisualStudio.Net2005命令提示下编译执行tlbimpc:/ProgramFiles/Dimac/w3JMail4/jmail.dll/out:myJmail.dll/namespace:myJmail
