如何用vb发邮件

'用系统内置的CDO组建发送邮件Dim NameS As String
Dim Email As Object
NameS = " http://schemas.microsoft.com/cdo/configuration/"
Set Email = CreateObject("CDO.Message")
Email.From = "12345@yahoo.cn" ' //你自己的油箱号码
Email.To = "1234@yahoo.cn" ' // 你自己的油箱号码（可以和上面相同）
Email.Subject = "" ' //相当于邮件里的标题
Email.Textbody = a & b '//相当于邮件里的内容
Email.Configuration.Fields.Item(NameS & "sendusing") = 2
Email.Configuration.Fields.Item(NameS & "smtpserver") = "smtp.yahoo.cn" '//邮件服务器(邮件服务器一定要对,要不然没用!)
Email.Configuration.Fields.Item(NameS & "smtpserverport") = 25 '//端口号
Email.Configuration.Fields.Item(NameS & "smtpauthenticate") = 1
Email.Configuration.Fields.Item(NameS & "sendusername") = "12345" '//油箱号码@前面的名字
Email.Configuration.Fields.Item(NameS & "sendpassword") = "123" '//你油箱的密码
Email.Configuration.Fields.Update
Email.Send

我用的是jmail组件发邮件的，给你个过程代码：Sub SendMail()
Dim jmail As Object
Set jmail = CreateObject("JMAIL.Message") ';建立发送邮件的对象
jmail.Silent = True ''一般不用改
jmail.Charset = "gb2312" ''信件的语言编码
jmail.ContentType = "text/html" ''信件的格式html或纯文本
jmail.From = "****@163.com" ''发信人邮箱
jmail.FromName = "****" ''发信人姓名
jmail.Subject = "" ''信件主题
jmail.AddRecipient "****" ''收信人地址
jmail.Body = "" ''信件正文
jmail.MailServerUserName = "****" ''服务器登陆用户名(您的邮件地址)
jmail.MailServerPassWord = "****" ''服务器登陆密码(您的邮件密码)
jmail.Send ("smtp.163.com") ''服务器地址
jmail.Close
Set jmail = Nothing
End Sub
不明白的再问

'收邮件
'有些服务器不支持jmail收发邮件，但163信箱肯定可以，自己测试一下
