邮件帐户中未收到ion auth忘记密码邮件

In ion auth我的忘记密码邮件已成功发送，但未在我的电子邮件帐户中收到。。。我搜索了很多教程，但找不到任何解决方案。

请帮我解决这个问题。

我的电子邮件配置文件

$config['email_config'] = array(
    'mailtype' => 'html',
    'protocol' => 'smtp',
    'smtp_host' => 'ssl://smtp.gmail.com',
    'smtp_port' => '465',
    'smtp_user' => 'k10kevalam@gmail.com',
    'smtp_pass' => 'k10@kevalam',
);

在_auth配置中

$config['use_ci_email'] = TRUE; // Send Email using the builtin CI email class, if false it will return the code and the identity
$config['email_config'] = 'file';

在_auth.php库中

if ($this->email->send())
		{
             echo $this->email->print_debugger();
             $this->set_message('forgot_password_successful');
	   		return TRUE;
        }

显示消息："已发送电子邮件"

在我的_auth.php控制器中

function forgot_password()
	{
            {
		   $this->form_validation->set_rules('email', $this->lang->line('forgot_password_username_identity_label'), 'required');
		}
		else
		{
		   $this->form_validation->set_rules('email', $this->lang->line('forgot_password_validation_email_label'), 'required|valid_email');
		}
		if ($this->form_validation->run() == false)
		{
			//setup the input
			$this->data['email'] = array('name' => 'email',
				'id' => 'email',
			);
			if ( $this->config->item('identity', 'ion_auth') == 'username' ){
				$this->data['identity_label'] = $this->lang->line('forgot_password_username_identity_label');
			}
			else
			{
				$this->data['identity_label'] = $this->lang->line('forgot_password_email_identity_label');
			}
			//set any errors and display the form
			$this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
			$this->_render_page('auth/forgot_password', $this->data);
		}
		else
		{
			// get identity from username or email
			if ( $this->config->item('identity', 'ion_auth') == 'username' ){
				$identity = $this->ion_auth->where('username', strtolower($this->input->post('email')))->users()->row();
			}
			else
			{
				$identity = $this->ion_auth->where('email', strtolower($this->input->post('email')))->users()->row();
			}
	            	if(empty($identity)) {
	            		if($this->config->item('identity', 'ion_auth') == 'username')
		            	{
                                   $this->ion_auth->set_message('forgot_password_username_not_found');
		            	}
		            	else
		            	{
		            	   $this->ion_auth->set_message('forgot_password_email_not_found');
		            	}
		                $this->session->set_flashdata('message', $this->ion_auth->messages());
                		redirect("auth/forgot_password", 'refresh');
            		}
			//run the forgotten password method to email an activation code to the user
			$forgotten = $this->ion_auth->forgotten_password($identity->{$this->config->item('identity', 'ion_auth')});
			if ($forgotten)
			{
				//if there were no errors
				$this->session->set_flashdata('message', $this->ion_auth->messages());
				
                                redirect("auth/login", 'refresh'); //we should display a confirmation page here instead of the login page
			}
			else
			{
				$this->session->set_flashdata('message', $this->ion_auth->errors());
                                				
                        redirect("auth/forgot_password", 'refresh');
			}
		}
	}

我该换什么。？

非常感谢您的帮助。
