发邮件可以.NET 自带的smtpmail类，但不能用于需要用户验证的SMTP服务器，方法见
msms-help://MS.MSDNQTR.2003FEB.2052/cpref/html/frlrfSystemWebMailSmtpMailClassTopic.htm
如要服务器验证，可以用自定义Socket或用微软的CDO组件
方法如下，引用CDO，在program files\common files\Microsoft shared\CDO下。能实现服务器验证。
public static bool SendEmail(string sendTo,string mailSubject,string mailContent,string account,string password,string smtp)
{
try
{
CDO.MessageClass cdoMsg = new CDO.MessageClass();
CDO.IConfiguration iConfig = cdoMsg.Configuration;
ADODB.Fields adoFields = iConfig.Fields;
// set the namespace prefix
string prefix = "http://schemas.microsoft.com/cdo/configuration/";
// set the adoFields
// you should get values from configuration file
// sending enumeration
// value = 1:send messages using local SMTP
// value = 2:send messages using network
adoFields[prefix + "sendusing"].Value=2;
// sendemailaddress:
// user's email address used when connecting to the SMTP service
adoFields[prefix + "sendemailaddress"].Value=account;
// smtpaccountname:
// user's Outlook Express account name
adoFields[prefix + "smtpaccountname"].Value=account;
string username = account.Substring(0,account.IndexOf("@"));
adoFields[prefix + "sendusername"].Value=username;
adoFields[prefix + "sendpassword"].Value=password;
//value=0 :Anonymous
//value=1 :basic (clear-text) authentication.
//The configuration sendusername/sendpassword or postusername/postpassword fields are used to specify credentials.）
//Value=2 NTLM（Secure Password Authentication in Microsoft Outlook Express）
adoFields[prefix + "smtpauthenticate"].Value=1;
adoFields["http://schemas.microsoft.com/cdo/configuration/languagecode"].Value=0x0804;
// smtpserver:you should get it from configuration file
adoFields["http://schemas.microsoft.com/cdo/configuration/smtpserver"].Value=smtp;
adoFields.Update();
// user's email
cdoMsg.To = sendTo;
// email from
// oMsg.From = " ";
// email subject
cdoMsg.Subject = mailSubject;
// email body
// put user's temporary password between <body> and </body>
cdoMsg.HTMLBody = "<html><body>Your new password is "+ mailContent+"</body></html>";
cdoMsg.Send();
}
