推荐答案

可以是由于各种原因.您需要一一看待它们.
港口开放吗?防火墙权限到位了吗?
进一步确保已在Web.Config中配置SMTP配置:

It can be because of various reasons. You need to look at them one by one.
Is the port open? Firewall permissions in place?
Further make sure you have configured SMTP configuration in Web.Config:

<system.net>
   <mailSettings>
     <smtp from="[e-mail]">
       <network host="somesmtpserver" port="25" userName="name" password="pass" defaultCredentials="true" />
     </smtp>
   </mailSettings>
</system.net>

如果需要，请查看此Microsoft Video教程:
使用ASP.NET发送来自网站的电子邮件 [

If needed, have a look at this Microsoft Video tutorial:
Use ASP.NET to send Email from Website[^]
Further, if needed, there are lots of article on this very site on how to send emails.

在web.config中

in the web.config

<appSettings>
<add key="SMTP" value="hostname.com"/>
<add key="FROMEMAIL" value="[e-mail]"/>
<add key="FROMEPWD" value="ur email pwd">
<add key="PORT" value="25">
</appSettings>

并使用以下代码发送邮件

and use following code to send the mail

protected bool Send(string To, string From, string Subj, string Msg)
    {
        try
        {
            string mFrom = From.ToString().Trim();
            string mTo = To.ToString().Trim();
            string mSubject = Subj.ToString().Trim();
            string mMsg = Msg.ToString().Trim();

            string mMailServer = ConfigurationManager.AppSettings.Get("SMTP");
            int mPort = Convert.ToInt32(ConfigurationManager.AppSettings.Get("PORT"));

            MailMessage message = new MailMessage(mFrom, mTo, mSubject, mMsg);
            SmtpClient mySmtpClient = new SmtpClient(mMailServer, mPort);
            // mySmtpClient.Credentials = new System.Net.NetworkCredential(ConfigurationManager.AppSettings["FROMEMAIL"], ConfigurationManager.AppSettings["FROMPWD"]);
            //mySmtpClient.EnableSsl = true;
            message.Priority = MailPriority.High;
            mySmtpClient.UseDefaultCredentials = true;
            mySmtpClient.Send(message);
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }
    }
