Fonction mail php avec authentification

Bonjour tous,

Je cherche une fonction mail php avec authentification pour tester mon smtp.
Je peux faire une recherche sur le net mais comme j'y connais rien, c'est au petit bonheur la chance, si j'en prend 1 qui fonctionne pas ou mal , les résultats seront faussé et je le verrais pas.

OHV me demande de mettre en ligne à la racine une fonction mail php avec authentification pour tester.
Si il remonte des erreur alors je dois ouvrir un ticket

car certains mails passent d'autres non avec l'erreur SMTP Error: Could not authenticate

Sur mon site WordPress, j'ai installé configure smtp.
le test que je viens de faire n'a pas fonctionné : il renvoi

Qu'est ce que cela signifie ?
Merci de votre aide

Je viens de trouver ce script qui me semble correspondre à la demande d'OVH.

<?php
// TEST FONCTION MAIL() PHP
// CREEZ UNE FICHIER email.php

// *** A configurer
$to = "adresse@machin.truc";  
$from  = "postmaster@bidule.truc";  

// *** Laisser tel quel
$jour  = date("d-m-Y");
$heure = date("H:i");

$sujet = "Essai Mail - $jour $heure";

$contenu = "";
$contenu .= "<html> \n";
$contenu .= "<head> \n";
$contenu .= "<title> Subject </title> \n";
$contenu .= "</head> \n";
$contenu .= "<body> \n";
$contenu .= "Mail au format HTML simple avec la fonction PHP mail().<br> <b>$sujet </b> <br> \n";
$contenu .= "</body> \n";
$contenu .= "</HTML> \n";

$headers  = "MIME-Version: 1.0 \n";
$headers .= "Content-Transfer-Encoding: 8bit \n";
$headers .= "Content-type: text/html; charset=utf-8 \n";
$headers .= "From: $from  \n";
// $headers .= "Disposition-Notification-To: $from  \n"; // accuse de reception

$verif_envoi_mail = TRUE;

$verif_envoi_mail = @mail ($to, $sujet, $contenu, $headers);
 
if ($verif_envoi_mail === FALSE) echo " ### Verification Envoi du Mail=$verif_envoi_mail - Erreur envoi mail <br> \n";
else echo " *** Verification Envoi du Mail=$verif_envoi_mail - Mail envoy&eacute; avec succ&egrave;s de $to vers $from <br> avec comme sujet: $sujet \n"; 
?> 

Mais il contient pas de demande d'identification par SMPT, non ?
Je n'ai renté null part mes parametres SMTP. !!!


Que dois rajouter ?
