使用CDO.Message对象就可以实现，示例代码演示的是gmail发送纯文本并带附件的邮件，至于其他的电子邮箱，需要修改代码中对应的smtp服务器和端口，原理也是一样的，就不举例了。贴出来的代码没有写注释，需要看注释的请下载源码。
Const Email_From = "still.demon@gmail.com"
Const Password = "password"
Const Email_To = "380401911@qq.com"
Set CDO = CreateObject("CDO.Message")
CDO.Subject = "From Demon"
CDO.From = Email_From
CDO.To = Email_To
CDO.TextBody = "Hello world!"
cdo.AddAttachment = "C:\hello.txt"
Const schema = "http://schemas.microsoft.com/cdo/configuration/"
With CDO.Configuration.Fields
.Item(schema & "sendusing") = 2
.Item(schema & "smtpserver") = "smtp.gmail.com"
.Item(schema & "smtpauthenticate") = 1
.Item(schema & "sendusername") = Email_From
.Item(schema & "sendpassword") = Password
.Item(schema & "smtpserverport") = 465
.Item(schema & "smtpusessl") = True
.Item(schema & "smtpconnectiontimeout") = 60
.Update
End With
CDO.Send
