Question

我从.net应用程序发送邮件，我的邮件代码工作正常，但我不想允许不正确的邮件ID。那么如何识别发送邮件的用户是否具有正确的ID。

我想知道smtpclient发送的邮件的响应。

    Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
    MailSettingsSectionGroup settings = (MailSettingsSectionGroup)config.GetSectionGroup("system.net/mailSettings");
     smtpHost = settings.Smtp.Network.Host;
     smtpport = settings.Smtp.Network.Port.ToString();
     smtpuser = settings.Smtp.Network.UserName;
     smtppwd = settings.Smtp.Network.Password;

    string MessageBody = string.Empty;
    try
    {

        message = new MailMessage();
        message.From = new MailAddress(smtpuser);

        message.To.Add(toMailAddress);

        message.BodyEncoding = System.Text.Encoding.UTF8;

        message.Subject = mailSubject;
        message.Body = mailMessage.ToString();



        message.IsBodyHtml = true;

        client = new SmtpClient();
        client.Host = smtpHost;
        //if (isSSLEnabled)
        //{
        //    client.EnableSsl = true;
        //}

        client.Port =  Convert.ToInt32(smtpport);
        client.EnableSsl = false;
        client.Credentials = new System.Net.NetworkCredential(smtpuser, smtppwd);

        client.Send(message);

    }
    catch (Exception ex)
    {
        string x = ex.Message;
    }

我会使用正则表达式来验证电子邮件。
