Phpmailer: SMTP Error: Could not connect to SMTP host. PHP 5.6.3

Created on 25 May 2015 · 9Comments · Source: PHPMailer/PHPMailer

Hello,
I'm trying to send mails from the local with gmail SMTP but it is impossible.
I use XAMPP for mac, PHP 5.6.3, Apache 2.4.10, OpenSSL 1.0.1j (is enabled in php.ini) and CodeIgniter.

i have this in the function

        $mail = new PHPMailer();
        $mail->IsSMTP(); // establecemos que utilizaremos SMTP
        $mail->SMTPDebug = 4;
        $mail->Debugoutput = 'html';
        $mail->SMTPAuth   = true; // habilitamos la autenticación SMTP
        $mail->SMTPSecure = "tls"; // establecemos el prefijo del protocolo seguro de comunicación con el servidor
        $mail->Host       = "smtp.gmail.com";      // establecemos GMail como nuestro servidor SMTP
        $mail->Port       = 587;                 // establecemos el puerto SMTP en el servidor de GMail

        $mail->Username   = "[email protected]";  // la cuenta de correo GMail
        $mail->Password   = "*********";            // password de la cuenta GMail

And I have this error:

  SERVER -> CLIENT: 220 2.0.0 Ready to start TLS
  ----------------------------------------------------------------------------------
  A PHP Error was encountered

  Severity: Warning

  Message: stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

  Filename: PHPMailer/class.smtp.php

  Line Number: 344
  ---------------------------------------------------------------------------------
  SMTP Error: Could not connect to SMTP host.

I searched a lot but i can't find the solution anywhere.
Thanks.

Thanks, i fixed it adding this code:

$mail->SMTPOptions = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);

This is covered in the troubleshooting guide. Your server is using an invalid or self-signed certificate and you're running PHP 5.6. The proper solution is to fix your server rather than disabling certificate checks.

OK, but do understand that this "fix" is to make your connection insecure.

Yes i know but is only for a project in the university, not for a real application. Thanks

Hi Synchro, could you suggest a way to fix my server settings. As I'm using the troubleshooting work around at present.

@10029759 figure out why you need the workaround - e.g. Whether you very has expired, is self-signed or whatever, and fix it. Then PHPMailer will be able to work properly.
