CodeIgniter Mail funktioniert nicht auf dem Server aber funktioniert gut localhost

Question

Ich benutze Shared Hosting-Plan. Ich habe mein Bestes versucht, aber ich kann dieses Problem nicht lösen. Hier ist mein Code. Ich versuchte zuerst mit gmail, aber arbeitete nicht, dann las ich irgendwo, dass die IP meines geteilten hosting-Plans von google dann schwarze Liste ist, ermüdete ich mein eigenes smtp dann imap Server, selbe Resultate funktioniert es gut auf localhost aber wieder bekomme ich das selbe Error.

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class Contact extends CI_Controller { 

    /** 
    * Index Page for this controller. 
    * 
    * Maps to the following URL 
    *  http://example.com/index.php/welcome 
    * - or - 
    *  http://example.com/index.php/welcome/index 
    * - or - 
    * Since this controller is set as the default controller in 
    * config/routes.php, it's displayed at http://example.com/ 
    * 
    * So any other public methods not prefixed with an underscore will 
    * map to /index.php/welcome/<method_name> 
    * @see http://codeigniter.com/user_guide/general/urls.html

ich diese Ausgabe

There is error in sending mail! Please try again later.

Answer 1

Zeile 73 des Code Sie auf dem Laufenden es sieht aus wie die if-Anweisung für

$this->email->send() 

schlägt fehl, was dann folgendes ausführt:

else 
    { 
     //error 
     echo $this->email->print_debugger(); 
     $this->session->set_flashdata('msg','<div class="alert alert-danger text-center">There is error in sending mail! Please try again later</div>'); 
     redirect('contact/index'); 
    } 

Ich würde die Konfiguration in email.php Check - in meinem Codeigniter 3 Projekt es sich hier:

html/system/libraries/Email.php 

Am Ende der this Codeigniter 3 API Seite einige Informationen über print_debugger und über die E-Mail Bibliothek. Es sollte dir helfen, in die richtige Richtung zu kommen.
