为什么不通过电子邮件库发送文件附件？

Question

为什么文件附件没有通过以下代码发送到预期的电子邮件？

$this->load->library('email');
$config = array();
$config['charset'] = 'utf-8';
$config['protocol']= "smtp";
$config['mailtype']= "html";
$config['smtp_host']= "mail.domain.com";
$config['smtp_port']= "25";
$config['smtp_timeout']= "5";
$config['smtp_user']= "xxxx";
$config['smtp_pass']= "xxxx";
$config['crlf']="\r\n";
$config['newline']="\r\n";
$config['wordwrap'] = TRUE;

$this->email->initialize($config);

$this->email->from('aaaa@bbb.com', 'Name');

$this->email->to('aaaa@bbb.com'); 

$this->email->attach(base_url('path/').$this->input->post('nm_file'));

$this->email->subject('This Subject');

$this->email->message("This Message");

if ($this->email->send()) {
  return true;
} else {
  show_error($this->email->print_debugger());
}

我尝试了各种方法，从更改端口和smtp等开始...

使用FCPATH路径代替基本URL：

尝试：

$this->email->attach(FCPATH."root_folder/folder/".$this->input->post('nm_file'));
