C#

MailMessage message = new MailMessage();
SmtpClient smtp = new SmtpClient("192.168.0.113",25);

message.From = new MailAddress("abc@123.com");
message.To.Add(new MailAddress("def@123.com"));
message.Subject = "Test";
message.Body = "Content";
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential("abc@123.com", "123456");
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(message);

Solution 1

Check your credentials and your port number: since you are using SSL, it's possible that you need a different port number, or that the port is blocked by firewall on one PC or another.

If that all looks right, try again without SSL and see if that makes any difference.
At the moment, you need to get information - so look at any inner exception as well - and we can't get that for you: we don't have access to your mail server!
