Cant send email to aol account from smtp relay server

I have a small program that sends email using the local smtp relay server.
I can send email to any other domain name (ie..yahoo or gmail or any other account)...but whenever i try to send the email to any valid (aol email) ...i dont see anything in the inbox.

but when i send it through my outlook or any gmail website itself...the message goes to the aol inbox.

any particular reason why it is behaving like this?


thanks
Albin


  string sMessage;
            SmtpClient smtpClient = new SmtpClient();
            MailMessage message = new MailMessage();
            try
            {

                //you can provide invalid from address. but to address Should be valil
                MailAddress fromAddress = new MailAddress("agorkhali@factortrust.com", "Albin");
                //smtpClient.Host = "192.168.100.11";

                smtpClient.Host = "192.168.200.50";
                smtpClient.Port = 25;
                //smtpClient.Port = 587;
                //smtpClient.EnableSsl = true;

                //smtpClient.UseDefaultCredentials = true; 
                //smtpClient.Credentials = nc;
                message.From = fromAddress;
            
                message.To.Add("gorkhalia@aol.com"); //Recipent email 
                message.Subject = "test smtp email";
                message.Body = "This is a test email through smtp client";
                message.IsBodyHtml = true;

                //smtpClient.EnableSsl = true; 
                smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
                smtpClient.Send(message);
                sMessage = "Email sent.";
            }
            catch (Exception ex)
            {
                sMessage = "Coudn't send the message!\n " + ex.Message;
            }

It could be because you are sending from a private IP address "192.168.200.50" instead of a known public IP address.  That is often taken as a sign of spam.  In addition, if AOL does a reverse lookup on your domain in the From address, it is clear that it's not the IP address associated with the factortrust.com mail servers.

You can ask your ISP to add a RDNS (Reverse DNS) record to your domain/IP.

In that way when AOL does a reverse lookup you have a fully valid RDNS record.
