I use PHPMailer, along with Apache and PHP, locally. When I test my SSL config and my cacerts I get
default_cert_file = C:\Program Files\Common Files\SSL/cert.pem
default_cert_file_env = SSL_CERT_FILE
default_cert_dir = C:\Program Files\Common Files\SSL/certs
default_cert_dir_env = SSL_CERT_DIR
default_private_dir = C:\Program Files\Common Files\SSL/private
default_default_cert_area = C:\Program Files\Common Files\SSL
ini_cafile =
ini_capath =
and then, I do
var_dump(fsockopen("smtp.gmail.com", 465, $errno, $errstr, 3.0));
var_dump($errno);
var_dump($errstr);
and I get
fsockopen resource(2) of type (stream) int(0) string(0) ""
In my php.ini
I have curl.cainfo = C:/php/cacert.pem
in the curl
part and it works.
But when I try to use PHPMailer to send a mail from localhost, I keep getting
SSL operation failed with code 1. OpenSSL Error messages:error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed
Failed to enable crypto
unable to connect to ssl://smtp.gmail.com:465 (Unknown error)
I also went to the account used in the SMTP, in https://accounts.google.com/DisplayUnlockCaptcha
and enable it. And to https://myaccount.google.com/lesssecureapps?pli=1
and enabled less secured apps.
I guess this is an SSL error and not a PHPMailer. Frankly, I am confused dont know how to fix it. Excuse my ignorance, any help on whats is going wrong and how to fix it , would be great.
PS, this my php file that sends the mail. Thank you
<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'C:/php/PHPMailer/src/Exception.php';
require 'C:/php/PHPMailer/src/PHPMailer.php';
require 'C:/php/PHPMailer/src/SMTP.php';
$mail = new PHPMailer(true);
try {
$mail->SMTPDebug = 3;
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->SMTPAuth = true;
$mail->Username = '[email protected]';
$mail->Password = 'secret';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465;
//Recipients
$mail->setFrom('[email protected]');
$mail->addAddress('[email protected]');
//Content
$mail->isHTML(true);
$mail->Subject = 'subject';
$mail->Body = 'HTML message body <b>in bold!</b>';
$mail->AltBody = 'body in plain text';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
}
?>
Update
When I try with $mail->SMTPSecure = 'ssl';
and $mail->Port = 465;
I get

Just had the same error message, maybe you've got the same issue:
stream_context_create
and stream_socket_client
Testing the same domain through cURL returned:
curl: (60) SSL certificate problem: certificate is not yet valid
Turns out my virtual machine in which I've run both PHP and cURL had 11 days of error (december 11th instead of december 22th).
By fixing the computer/virtual machine's date (using ntp
, ntpdate-debian
or the like), the certificate test now runs fine, in both cURL command-line or PHP.
