Solution 1

Does smtp.website.com exist, or did you copy this off the web ? You need to change this code to point to an actual mail server. You also should tell us the actual error message, if you want us to decode it for you.

This error means that you have a real mail server, but it is refusing your connection, either because your settings are wrong, such as requiring a username and password, or requiring SSL, or your server is rejecting your connection for other reasons, such as, some ISPs will only let you use their mail server, if you are logged in to the internet through their servers. I would suggest getting a gmail account, and reading up on how to send mail through gmail, or hotmail, or similar. If you have a server you know works for other people, you eliminate that as an issue.

Solution 2

What is the actual error you are getting?
Check whether your smtp server supports SSL and Authentication,

if (_ssl == "SSL")
{
    smtpClient.EnableSsl = true;
}
else
{
    smtpClient.EnableSsl = false;
}
if (_isauthenticate == "Yes")
{
    smtpClient.UseDefaultCredentials = false;
    credentials =
            new System.Net.NetworkCredential(str_user, str_password);

    smtpClient.Credentials = credentials;
}
else
{
    smtpClient.UseDefaultCredentials = true;
    credentials =
            new System.Net.NetworkCredential();
    smtpClient.Credentials = credentials;

}

Hope this helps.
cheers

check the port. Best idea is to open your gmail account and check the smtp settings.
