You need to set smtp.EnableSsl = true for gmail.

Take a look at this class, it should work for you:

public class Email
{
    NetworkCredential credentials;
    MailAddress sender;

    public Email(NetworkCredential credentials, MailAddress sender)
    {
        this.credentials = credentials;
        this.sender = sender;
    }

    public bool EnableSsl
    {
        get { return _EnableSsl; }
        set { _EnableSsl = value; }
    }
    bool _EnableSsl = true;

    public string Host
    {
        get { return _Host; }
        set { _Host = value; }
    }
    string _Host = "smtp.gmail.com";

    public int Port
    {
        get { return _Port; }
        set { _Port = value; }
    }
    int _Port = 587;

    public void Send(MailAddress recipient, string subject, string body, Action action, params FileInfo[] attachments)
    {
        SmtpClient smtpClient = new SmtpClient();

        // setup up the host, increase the timeout to 5 minutes
        smtpClient.Host = Host;
        smtpClient.Port = Port;
        smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
        smtpClient.UseDefaultCredentials = false;
        smtpClient.Credentials = credentials;
        smtpClient.Timeout = (60 * 5 * 1000);
        smtpClient.EnableSsl = EnableSsl;

        using (var message = new MailMessage(sender, recipient)
        {
            Subject = subject,
            Body = body
        })
        {
            foreach (var file in attachments)
                if (file.Exists)
                    message.Attachments.Add(new Attachment(file.FullName));
            if(null != action)
                action(message);
            smtpClient.Send(message);
        }
    }
}
