The error is self-explanatory. Either there is no smtp server listening on that port at that address, it is not running properly, or there is a network\firewall issue between your webserver and the smtp server. Either way it's network or configuration, not code. Contact the people responsible for the smtp server and ask if there is anything specific you need to do such as authenticate etc, use ssl etc and have your code match what the server needs.

Try below code to send mail using gmail.

C#

public string senMail(string emailId, string MailBody)
        {
            try
            {
                MailMessage mail = new MailMessage();
                SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com"); //Gmail SMTP Client

                mail.From = new MailAddress("abc@gmail.com"); //Sender email ID 
                mail.To.Add(emailId);
                mail.Subject = "Email Subject";
                mail.Body = mailBody;
 
                SmtpServer.Port = 587;
                SmtpServer.Credentials = new System.Net.NetworkCredential("abc@gmail.com", "abc152wte.7"); //Sender email and password (login credential)
                SmtpServer.EnableSsl = true;
                SmtpServer.Send(mail);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }
            return "";
        }
