How do I send mail using C#?

Here is the code snippet I found...

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("luckyperson@online.microsoft.com");
message.Subject = "This is the Subject line";
message.From = new System.Net.Mail.MailAddress("From@online.microsoft.com");
message.Body = "This is the message body";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("yoursmtphost");
smtp.Send(message);

Not that everyone cares, just that maybe one or two do. Here's how to post an email to an Exchange Server mailbox over http using WebDAV.

public static void SendEmail(string server, string mailbox, string password, string to, string subject, string body, bool secureHttp)
{
string httpProtocol = secureHttp ? "https://" : "http://";
string mailboxUri = httpProtocol + server + "/" + mailbox;
string submissionUri = httpProtocol + server + "/" + mailbox + "/##DavMailSubmissionURI##/";
string draftsUri = "http://" + server + "/" + mailbox + "/drafts/" + subject + ".eml";

string message = "To: " + to + "\n" +
"Subject: " + subject + "\n" +
"Date: " + System.DateTime.Now +
"X-Mailer: mailer" + "\n" +
"MIME-Version: 1.0" + "\n" +
"Content-Type: text/plain;" + "\n" +
"Charset = \"iso-8859-1\"" + "\n" +
"Content-Transfer-Encoding: 7bit" + "\n" +
"\n" + body;

// Credentials for exchange requests.
CredentialCache credentials = new CredentialCache();
credentials.Add(new Uri(mailboxUri), "NTLM", new NetworkCredential(mailbox, password));

// Request to put an email the drafts folder.
HttpWebRequest putRequest = (HttpWebRequest)HttpWebRequest.Create(draftsUri);
putRequest.Credentials = credentials;
putRequest.Method = "PUT";
putRequest.ContentType = "message/rfc822";

byte[] bytes = Encoding.UTF8.GetBytes((string)message);
putRequest.ContentLength = bytes.Length;

Stream putRequestStream = putRequest.GetRequestStream();
putRequestStream.Write(bytes, 0, bytes.Length);
putRequestStream.Close();

// Put the message in the Drafts folder of the sender's mailbox.
WebResponse putResponse = (HttpWebResponse)putRequest.GetResponse();
putResponse.Close();

// Request to move the email from the drafts to the mail submission Uri.
HttpWebRequest moveRequest = (HttpWebRequest)HttpWebRequest.Create(draftsUri);
moveRequest.Credentials = credentials;
moveRequest.Method = "MOVE";
moveRequest.Headers.Add("Destination", submissionUri);

// Put the message in the mail submission folder.
WebResponse moveResponse = (HttpWebResponse)moveRequest.GetResponse();
moveResponse.Close();
}

This was helful,

but the only problem that I face is authentication, so please provide an explicit example.

Let us say for instance that my e-mail (from field) is: "from@yahoo.com" with user name: "from" and password: "password", and I am sending to: "to@hotmail.com".

That is what I am trying to do for months ...

Thanks a lot
