Issue sending email using c#

[hamoon]

i'm trying to send an email using the code below :

SmtpClient smtpClient = new SmtpClient();
            MailMessage message = new MailMessage();

            MailAddress fromAddress = new MailAddress("info@jabe-abzar.com", "From Name");

       
            smtpClient.Host = "mail.jabe-abzar.com";

         
            smtpClient.Port = 25;

            NetworkCredential info = new NetworkCredential("info@jabe-abzar.com", "my pass");
            smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtpClient.UseDefaultCredentials = false;
            smtpClient.Credentials = info;

         
            message.From = fromAddress;

       
            message.To.Add("hamoonshahsavar@gmail.com");
            message.Subject = "Your subject";

         

         
            message.IsBodyHtml = false;

     
            string ss_body = "body of email is here";
            message.Body = ss_body;

       


            smtpClient.Send(message);

but i'm getting "{"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 185.159.152.16:25"}" error on last line " smtpClient.Send(message);;".
is there any settings that i should do in my panel?
is this even the right way to send an email?
