测试过了，已经通过了

<%@ Page Language="C#" %>

<%@ Import Namespace="System.Net.Mail" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

protected void Button1_Click(object sender, EventArgs e)
{
System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();

msg.From = new MailAddress("yuzhen20@126.com");
msg.To.Add(new MailAddress(TextBox1.Text));

msg.Subject = TextBox2.Text;
msg.Body = TextBox3.Text;
string attachFile;
attachFile=FileUpload1.FileName;

System.Net.Mail.Attachment mailadd = new Attachment(FileUpload1.PostedFile.InputStream, attachFile);

msg.Attachments.Add(mailadd);

SmtpClient smt = new SmtpClient();
smt.Send(msg);

}
</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server" Text="收件人地址："></asp:Label>
<asp:TextBox ID="TextBox1" runat="server" Width="216px"></asp:TextBox><br />
<br />
<asp:Label ID="Label2" runat="server" Text="主题："></asp:Label>
<asp:TextBox ID="TextBox2" runat="server" Width="219px"></asp:TextBox><br />
<br />
<asp:Label ID="Label4" runat="server" Text="附件："></asp:Label>

<asp:FileUpload ID="FileUpload1" runat="server" /><br />
<br />
<asp:Label ID="Label3" runat="server" Text="内容："></asp:Label><br />
<asp:TextBox ID="TextBox3" runat="server" Height="176px" Width="348px"></asp:TextBox><br />

<asp:Button ID="Button2" runat="server" Text="取消" /></div>
</form>
</body>
</html>

然后在web.config里面配置下：
<?xml version="1.0"?>
<configuration>
<system.net>
／／配置smtp
<mailSettings>
<smtp deliveryMethod="Network" from="yuzhen20@126.com">
<network defaultCredentials="false" host="smtp.126.com" port="25" userName="yuzhen20" password="tramper11"/>

</smtp>
</mailSettings>
</system.net>

<connectionStrings/>
<system.web>
<globalization requestEncoding="gb2312" responseEncoding="gb2312"/>
<compilation debug="true"/>
<authentication mode="Windows"/>

<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
</system.web>
</configuration>

2005——

string server="smtp.163.com";
string file = "e:\xxx.rar";
MailMessage message = new System.Net.Mail.MailMessage("xxx@163.com", "yyy@163.com", "正文", "标题");
Attachment data = new System.Net.Mail.Attachment(file, System.Net.Mime.MediaTypeNames.Application.Octet);
System.Net.Mime.ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = File.GetCreationTime(file);
message.Attachments.Add(data);
SmtpClient client = new SmtpClient(server);
client.Credentials = new NetworkCredential("用户名", "密码");
client.Send(message);
data.Dispose();

vs2003 引用 System.Web.Mail命名空间
vs2005 引用 System.Net.Mail命名空间,安全性得到了增强

...
try
{
//创建邮件消息
MailMessage objMailMessage = new MailMessage();
objMailMessage.From = System.Configuration.ConfigurationSettings.AppSettings["mailfrom"];//源邮件地址"xxx@163.com"
objMailMessage.To = System.Configuration.ConfigurationSettings.AppSettings["mailto"];//目的邮件地址"yyy@163.com"
objMailMessage.Subject = "邮件的标题";//发送邮件的标题
objMailMessage.Body = "邮件的内容";//发送邮件的内容

string user = System.Configuration.ConfigurationSettings.AppSettings["mailuser"];//源邮件地址用户名
string psw = (System.Configuration.ConfigurationSettings.AppSettings["mailpsw"]);//源邮件地址用户密码
