// Create a new instance of the MailMessage class.
MailMessage mailMessage = new MailMessage();
mailMessage.From.Add("from@thedomain.com");
mailMessage.To.Add("sfbmailtest@gmail.com");
mailMessage.Subject = "Mail Message Test Subject";
mailMessage.BodyText = "Mail Message Test Content";

// Initialize security settings.
TlsSslSecuritySettings ss = new TlsSslSecuritySettings();
ss.ServerName = serverName;
ss.CertificateValidator =
            CertificateValidators.AcceptAllValidator;
// Allows all suites.
ss.Suites = TlsSslCipherSuite.All;
// Supports SSL3.0 and TLS1.0.
ss.ProtocolVersion = TlsSslProtocolVersionFlag.SSL30
                    | TlsSslProtocolVersionFlag.TLS10;

Console.WriteLine("Connecting SMTP server: {0}:{1}...",
                    serverName, port);
// Connect to the server.
SmtpClient client = new SmtpClient();
client.Connect(serverName, port, ss, securityMode);

// Login to the server.
Console.WriteLine("Logging in as {0}...", user);
client.Login(user, password);

Console.WriteLine("Sending message...");
client.Send(mailMessage);
Console.WriteLine("Message sent...");

// Disconnect.
