推荐答案

检查防火墙并确保未阻止防火墙您希望从中发送电子邮件的端口.

Check for firewall and make sure it is not blocking the port from which you wish to send the email.

您正在尝试从相当长的一段时间开始使用此功能.

可能是由于各种原因.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:

You are trying to have this feature from quite some time now.

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[^]

public bool SendEmail(string senderEmail, string receiverEmail, string subject, string body)
{
try
{
//MailAddress emailto = senderEmail;
MailAddress emailto = new MailAddress(receiverEmail);
//MailAddress emailfrom = receiverEmail;
MailAddress emailfrom = new MailAddress(senderEmail);
MailMessage mail = new MailMessage(senderEmail, receiverEmail);
mail.Subject = subject;

mail.Body = body;
mail.IsBodyHtml = true;
NetworkCredential basicCredential = new NetworkCredential("UserName", "Password");
SmtpClient objSmtpClient = new SmtpClient(HostAddress,PortNo);

objSmtpClient.Credentials = basicCredential;



objSmtpClient.Send(mail);
}
catch
{
return false;
}
return true;
}

停止防火墙访问保护
