problema con el envio de correo utilizando phpMailer

[Montes28]

hola amigos del foro espero me puedan ayudar

tengo una aplicacion que envia correos , como prueba estoy enviando correos por hotmail y toda va perfecto el inconveniente es que la aplicacion tiene que enviar correo por el correo interno de la empresa

este es el codigo que estoy utilizando

Código PHP:

$correo = $_POST['email'];
 
 
 
  require_once('phpMailer/class.phpmailer.php'); 
 
  require_once("phpMailer/class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded
 
 
 
  $mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch
 
  $mail->IsSMTP(); // telling the class to use SMTP
 
  $mail->Host       = 'smtp.live.com'; // SMTP server
 
  $mail->SMTPDebug  = 0;                     // enables SMTP debug information (for testing)
 
  $mail->SMTPAuth   = true;                  // enable SMTP authentication
 
  $mail->Host       = 'smtp.live.com'; // sets the SMTP server
 
  $mail->SMTPSecure = 'tls';
 
  $mail->Port       = 25;                    // set the SMTP port for the GMAIL server
 
  $mail->Username   = '[email protected]'; // SMTP account username
 

para el nuevo requerimiento cambie las siguientes lineas

$mail->Host = 'smtp.live.com'; // aca estoy colocando el servidor de correo de la empresa
y

$mail->Username = 'omontes@correo'; y aca el correo que tengo en mi empresa desde donde voy a enviar le correo

me aparece el siguiente error , que puede ser ?

Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.
