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。

代码如下:

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

详细注释版:

代码如下:

'Date: 2010/6/18

'Author: Demon

'QQ: 380401911

'E-mail: still.demon@gmail.com

'Website: http://demon.tw

Const Email_From = "ddd@163.com" '发件人邮箱

Const Password = "password" '发件人邮箱密码

Const Email_To = "380401911@qq.com" '收件人邮箱

Set CDO = CreateObject("CDO.Message") '创建CDO.Message对象

CDO.Subject = "From Demon" '邮件主题

CDO.From = Email_From '发件人地址

CDO.To = Email_To '收件人地址

CDO.TextBody = "Hello world!" '邮件正文

cdo.AddAttachment = "C:\hello.txt" '邮件附件文件路径

Const schema = "http://schemas.microsoft.com/cdo/configuration/" '规定必须是这个，我也不知道为什么

With CDO.Configuration.Fields '用with关键字减少代码输入

.Item(schema & "sendusing") = 2 '使用网络上的SMTP服务器而不是本地的SMTP服务器

.Item(schema & "smtpserver") = "smtp.gmail.com" 'SMTP服务器地址

.Item(schema & "smtpauthenticate") = 1 '服务器认证方式

.Item(schema & "sendusername") = Email_From '发件人邮箱

.Item(schema & "sendpassword") = Password '发件人邮箱密码

.Item(schema & "smtpserverport") = 465 'SMTP服务器端口

.Item(schema & "smtpusessl") = True '是否使用SSL

.Item(schema & "smtpconnectiontimeout") = 60 '连接服务器的超时时间

.Update '更新设置

End With

CDO.Send '发送邮件
