如果选择了163的SMTP服务器,“smtp.163.com”，发件人必须是登录用户的163 email用户地址。


System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.163.com");


smtp.Credentials = new System.Net.NetworkCredential("163emailaddress","emailpassword");




System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();


message.From = new System.Net.Mail.MailAddress("163emailaddress@163.com");



web.config加入

 <system.net>
  <mailSettings>
   <smtp from="163emailaddress@163.com">
    <network host="smtp.163.com" password="*****" port="25" userName="username" defaultCredentials="false"/>
   </smtp>
  </mailSettings>
 </system.net>

 

以下为VB.NET代码

Dim message As New MailMessage()
            '收件人
            message.To.Add("one@21cn.com")
            '主题
            message.Subject = "使用.NET 2.0发送邮件"
            message.From = New MailAddress("163emailaddress@163.com")
            message.Body = "非常简单"
            Dim m_smtpClient As New SmtpClient("smtp.163.com")
            m_smtpClient.Send(message)
