SMTP ERROR: Failed to connect to server: Permission denied (13)

Question

Good day!

Im trying to make my phpmailer work in my shared hosting (freehostia.com) and I always get this error. The username and password of my gmail is correct, and the rest of the settings is like this:

$mail = new PHPMailer;

$mail->isSMTP();
$mail->SMTPDebug  = 2;
$mail->Host       = 'tls://smtp.gmail.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth   = true; // Enable SMTP authentication
$mail->Username   = 'mymail@gmail.com'; // SMTP username
$mail->Password   = 'mypassword'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port       = 587; // TCP port to connect to

$mail->setFrom('mymail@gmail.com', 'ASAPHOT Administrator'); // Add a recipient
$mail->addAddress('sorianorobertc@gmail.com'); // Name is optional
$mail->addReplyTo('mymail@gmail.com', 'ASAPHOT Administrator');

$mail->isHTML(true); // Set email format to HTML

$mail->Subject = 'it works';
$mail->Body    = 'it works';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if (!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

openssl is uncommented in the php.ini also. Am I missing something here? Thank you.

Answer 1

Let's get to the answer first of all! Try with the following command:

$ getsebool httpd_can_sendmail

if it shows: httpd_can_sendmail --> off

switch it on with this:

$ sudo setsebool -P httpd_can_sendmail 1

then try sending the email again.

This solution comes from this great page .

As it was pointed out from this article, you may also need to try sudo setsebool -P httpd_can_network_connect 1 . While for my CentOS 7 vm hosted by DigitalOcean, it's not necessary.

The problem I met was failing to send out emails from a Drupal website, with the SMTP Authentication Support module, which relies on PHPMailer underneath. And the SMTP server used was Google.

BTW, I had suspected it was OpenSSL certificate problem and did some test but no luck. So by setting the $SMTPDebug level to 2 from the PHPMailer source code, I was able to capture the "Permission denied (13)" error message.

Answer 2

This suggests that fopen wrappers or socket functions are disabled in your PHP installation. Not unusual in shared hosting. Running phpinfo() should tell you.

You can probably use $mail->isMail(); and skip the auth to send via the ISP's mail server instead of SMTP, but beware of SPF issues.

Answer 7

use this
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "ssl"; // sets the prefix to the servier
$mail->Host = "ssl://smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = 465; // set the SMTP port

if this not working than try bellow for php code.

mail($to,$subject,$message);
