How to send emails from my website domain in asp.net - asp.net

Question

I want to send mail from my website domain(www.sample.com)
I have written below code. It is not returning any error. But it is not sending mail once I uploaded the pages in the server. Once click on email send, it is not getting any error, but not receiving the mail.
System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient("mail.sample.co.uk", 25);
smtpClient.Credentials = new System.Net.NetworkCredential("smtpuser#sample.co.uk", "pass#123");
smtpClient.UseDefaultCredentials = true;
smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = false;
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
//Setting From , To and CC
mail.From = new System.Net.Mail.MailAddress("smtpuser#sample.co.uk", "MyWeb Site");
mail.To.Add(new System.Net.Mail.MailAddress("myemail#gmail.com"));
mail.CC.Add(new System.Net.Mail.MailAddress("myemail1#gmail.com"));
smtpClient.Send(mail);
I am getting the "mailsend" response text in the page once calling the sending method.
Please help

The following code works perfect for me. Make sure you have added a mail account on the smtp server and activated it.
private static string EMAIL_SERVER = "mailservername.mydomain.com";
private static string EMAIL_NAME = "myMailAccount#mydomain.com";
private static string EMAIL_PASSWORD = "complex_password123";
private static string EMAIL_SEND_TO = "sample#mail.com";
protected string SendMail()
{
try
{
System.Net.Mail.MailMessage objMM = new System.Net.Mail.MailMessage();
objMM.From = new MailAddress("fromMe#mail.com", "john doe");
objMM.To.Add(new MailAddress(EMAIL_SEND_TO)); //Note: this To a collection
objMM.Subject = "Subject1";
objMM.Body = "Hello world this is my text";
objMM.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient(EMAIL_SERVER);
smtp.Credentials = new NetworkCredential(EMAIL_NAME, EMAIL_PASSWORD);
smtp.Send(objMM);
}
catch (Exception e)
{
return "Message can not be send couse of error: " + e.ToString();
}
return "Message is send.";
}
