Answer 2

把("发件箱","收件箱","主题","内容")丢给这个东西就OK了
需要注意的是.smtp.163.com的东西需要匹配下面的邮箱.    public void sendmail(string senduser, string recuser, string sub, string str)
    {
        if (senduser != null && recuser != null)  //Send User & Receive User must be not null
        {
            System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.163.com");
            smtp.Credentials = new System.Net.NetworkCredential("***@163.com", "****");
            smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
            System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage(senduser, recuser, sub, str);
            msg.BodyEncoding = System.Text.Encoding.UTF8;
            msg.IsBodyHtml = true;            try
            {
                smtp.Send(msg); //send mail 
            }
            catch (Exception err)
            {
                return; //return to page
            }        }
        else
            return;
    }
