通过ci框架mail邮件类发送邮件和利用利用第三方平台发送邮件
1、controller
public function mail()
{
    $param = array();
    $param['to'] = 'qing.chen';
    $param['subject'] = '邮件测试-标题';
    //$param['tmpl'] = 'email/demo';
    $param['content'] = "111";
      
    $this->MailModel->sendMail($param);      
    echo 'sss';      
}

2、model
class MailModel extends CI_Model
{
    /**
     * 生成邮件内容
     *
     * @param string $templ
     * @param array $data
     * @return string
     * @author http://blog.iwshop.com/
 
     */
    public function makeBody($tmpl, $data)
    {
        $content = $this->load->view($tmpl, $data, true);
        return $content;
    }
      
  /**
   * 发送邮件
   *
   * @param array $param
   * @return boolean
   */
  public function sendMail($param)
  {
      // 发件人配置
      if ( empty($param['frommail']))   $param['frommail'] = 'woims';
      if ( empty($param['fromname'])) $param['fromname'] = '运营平台';
      $param['frommail'] = $this->_domain($param['frommail']);
    
      // CI mail 配置
      $this->load->library('email');     
        $config = array();
        $config['protocol'] = 'smtp';   // 邮件协议
        $config['smtp_host'] = 'ssl://smtp.qq.com';
        $config['smtp_user'] = '你的@qq.com';
        $config['smtp_pass'] = '授权码';//去QQ邮箱设置开启smtp
        $config['smtp_port'] = 465; //邮箱端口
        $config['smtp_timeout'] = 30;   //超时时间
        $config['mailtype'] = 'text';   // 格式 (text/html)
        $config['charset'] = 'utf-8';   // 编码
        $config['wordwrap'] = TRUE; // 自动换行
        $this->email->initialize($config);
        $this->email->set_newline("\r\n");
        $config['crlf'] = "\r\n";
       
     //$param['cc'] = 'barly.li,qingbin.wu';
        
      $this->email->from($param['frommail'], $param['fromname']);
      if ( $param['to'])  $this->email->to($this->_domain($param['to']));
      //if ( $param['cc'])  $this->email->cc($this->_domain($param['cc']));//抄送
      //if ( $param['bcc']) $this->email->bcc($this->_domain($param['bcc']));//密送
        
      //如果存在邮件模板使用模板作为邮件内容 2015-01-08
      $param['content'] = $param['tmpl'] ? $this->makeBody($param['tmpl'], $param['data']) : $param['content'];
        
      $this->email->subject($param['subject']);
      $this->email->message($param['content']);
      $this->email->send();
      return true;
  }
