asp.net发送邮件的方式不少，我经常用这样两种：
一，System.Web.Mail 和System.Web.Util

public static void SendMail(string from , string to, string subject, string body)
        {
            MailMessage email = new MailMessage();
            email.From  = from;
            email.To = to;
            email.Subject  = subject;
            email.Body = body;
            SmtpMail.Send(email);    
        }
二 ，利用组件 adodb和cdo
public static void CDOsendmail(string from, string to, string subject, string body, string userName, string password, string smtpServer)
        {
            
                CDO.Message Msg = new CDO.Message();
                Msg.From = from;
                Msg.To = to;
                Msg.Subject = subject;
                Msg.HTMLBody = "<html><body>"+body
                    +"</body></html>";
                CDO.IConfiguration Config = Msg.Configuration;
                ADODB.Fields oFields = Config.Fields;
                oFields["http://schemas.microsoft.com/cdo/configuration/sendusing"].Value = 2;
                oFields["http://schemas.microsoft.com/cdo/configuration/sendusername"].Value=userName;
                oFields["http://schemas.microsoft.com/cdo/configuration/sendpassword"].Value=password; 
                oFields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"].Value=1;
                oFields["http://schemas.microsoft.com/cdo/configuration/languagecode"].Value=0x0804;
                oFields["http://schemas.microsoft.com/cdo/configuration/smtpserver"].Value=smtpServer;
                oFields.Update();

                Msg.BodyPart.Charset = "gb2312";
                Msg.HTMLBodyPart.Charset = "gb2312";


                Msg.Send();
                Msg = null;
            
            
        }

两种方式的成功率差距很大，后者很高。
