localhost is just an example. You need to fill out the hostname of a valid SMTP server. Check with your mail provider for more information.

This error means the SMTP server that you are using requires authentication.
You can enter your username/password details with this code.
Code: Select allsc->Credentials = gcnew System::Net::NetworkCredential("user", "pass");
You may also need to set sc->EnableSsl to true.
Once again, check with your mail provider as they can tell you what the right security settings will be.

In order to connect to certain SMTP servers you will need a user name and password (usually given when you register an account with the provider). Without authentication anyone could use the server to send spam emails.
