哪里有好用的asp.net 用户找回密码代码

用户忘记密码，想用用户的email来找回密码，哪里有发送密码到用户邮箱的代码？
网上找的都发不出去，听说是邮件服务器的问题，哪里有免费的可以发信的邮箱申请？

那就从邮件服务器的问题出发。换一个G-mail的试试。
private bool sendMail(string to, string title, string content)
        {
            SmtpClient _smtpClient = new SmtpClient();
            _smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;//指定电子邮件发送方式
            _smtpClient.Host = fromSmtp; ;//指定SMTP服务器

            _smtpClient.Credentials = new System.Net.NetworkCredential(fromUser, fromPwd);//用户名和密码            MailMessage _mailMessage = new MailMessage(from, to);
            _mailMessage.Subject = title;//主题
            _mailMessage.Body = content;//内容
            _mailMessage.BodyEncoding = System.Text.Encoding.UTF8;//正文编码
            _mailMessage.IsBodyHtml = true;//设置为HTML格式
            _mailMessage.Priority = MailPriority.High;//优先级
            if (!string.IsNullOrEmpty(mailCC))
            {
                _mailMessage.CC.Add(mailCC);
            }
            try
            {
                _smtpClient.Send(_mailMessage);

                return true;
            }
            catch(Exception ex)
            {

                return false;

jmail.Message 这个控件我没有，请问哪里有下载？
使用Interop.jmail.dll组件
jmail.Message Jmail = new jmail.Message();
string strPath = System.Web.HttpContext.Current.Server.MapPath("~/a.html");
StreamReader sr = new StreamReader(strPath, System.Text.Encoding.Default);
StringBuilder body = new StringBuilder();
body.Append(sr.ReadToEnd());
sr.Close();
string FromEmail = "[email protected]";
string ToEmail = "";
Jmail.Silent = true;
Jmail.Logging = true;
Jmail.Charset = "GB2312";
Jmail.ContentType = "text/html";
Jmail.AddRecipient(ToEmail, "", "");
Jmail.From = FromEmail;
Jmail.MailServerUserName = "";
Jmail.MailServerPassWord = "";
Jmail.Subject = Subject;
Jmail.ContentType="text/html";
Jmail.Body = body.ToString().Trim();
Jmail.Send("smtp.a.com", false);
Jmail.Close(); http://topic.csdn.net/u/20091030/13/8f8b778f-4b38-4d72-8569-960f4d7848ac.html
visual studio 2005中的ASP.NET好像有完整的找回密码模块，可以直接使用。
我们以前用的时候好像都是直接采用的。
至于找回密码的发件服务器好像根本不用，那个找回密码模块里面去配置个服务器出来就成，只是需要输入一个发件邮箱就行了
