配置Web站点发送电子邮件

    <system.net>
        <mailSettings>
            <smtp deliveryMethod="Network" from="cuisl &lt;cuisl@139.com&gt;">
                <network host="smtp.139.com"  userName="cuisl" password="******"/>
            </smtp>
        </mailSettings>
    </system.net>

直接将邮件放到本地磁盘

      <smtp deliveryMethod="SpecifiedPickupDirectory">
        <specifiedPickupDirectory pickupDirectoryLocation="C:\TempMail" />
      </smtp>

需要用到的空间：

Imports System.Net.Mail

发送邮件的代码：

    Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        Dim myMessage As MailMessage = New MailMessage()
        myMessage.Subject = "Test Message"
        myMessage.Body = "Hello world, from Planet Wrox"
        myMessage.From = New MailAddress("cuisl@139.com", "cuisl")
        myMessage.To.Add(New MailAddress("xp44m@yahoo.com.cn", "xp44m"))
        Dim mySmtpClient As SmtpClient = New SmtpClient()
        mySmtpClient.Send(myMessage)
    End Sub
