Codeigniter Email error handling

Question

The CI Email send() function only returns true or false. Is there a way to get a more detailed reason as to why a sending failed? I\'m using SMTP.

You can further inspect what happened by using the email debugger:

$r = $this->send(FALSE);
if (!$r)
  $this->email->print_debugger()
  ;

From the Codeigniter Email Class Reference.

If you need the debugger output as a string, you can just catch the output with an output buffer:

$errors = array();
... # Loop
$r = $this->send(FALSE);
if (!$r) {
  ob_start();
  $this->email->print_debugger();
  $error = ob_end_clean();
  $errors[] = $error;
}
... # Loop end

Codeigniter in more recent versions requires an explicit FALSE for the $auto_clear parameter of the email->send() function in order to not clear the message and the debugging, effectively killing the debugger function if you fail to pass the FALSE.
