Cant send mails with PHPMailer

[telmark]

I can not send mails (I want to send them directly from Gmail, not with the mail () function), I'm trying the PHPMailer library and when I run it from a URL It does not work, it disconnects me from the server in the middle of the connection. If I do from SSH, with the root user, all right, send the mails correctly.
The option: whm > security center > SMTP Restrictions is Disable.
Now if I run from the browser that same, it does not work:
In: /var/log/apache2/error_log does not register errors.

And the PHP script returns:
    2017-07-30 21:46:54 SERVER -> CLIENT: 220-hosting.xxxx.cl ESMTP Exim 4.89 # 1 Sun, 30 Jul 2017 17:46:54 -0400 220-We do not authorize the use of this system To transport unsolicited, 220 and / or bulk email.

It seems that you are just starting to send the mail, close the connection. What can be the problem?


The code of the script is the follow:

<?php
/**
 * This example shows settings to use when sending via Google's Gmail servers.
 */

//SMTP needs accurate times, and the PHP time zone MUST be set
//This should be done in your php.ini, but this is how to do it if you don't have access to that
date_default_timezone_set('Etc/UTC');

require '../PHPMailerAutoload.php';

//Create a new PHPMailer instance
$mail = new PHPMailer;

//Tell PHPMailer to use SMTP
$mail->isSMTP();

//Enable SMTP debugging
// 0 = off (for production use)
// 1 = client messages
// 2 = client and server messages
$mail->SMTPDebug = 2;

//Ask for HTML-friendly debug output
$mail->Debugoutput = 'html';

//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';
// use
// $mail->Host = gethostbyname('smtp.gmail.com');
// if your network does not support SMTP over IPv6

//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
$mail->Port = 587;

//Set the encryption system to use - ssl (deprecated) or tls
$mail->SMTPSecure = 'tls';

//Whether to use SMTP authentication
$mail->SMTPAuth = true;

//Username to use for SMTP authentication - use full email address for gmail
$mail->Username = "[email protected]";

//Password to use for SMTP authentication
$mail->Password = "xxxxxxx";

//Set who the message is to be sent from
$mail->setFrom('[email protected]', 'First Last');

//Set an alternative reply-to address
$mail->addReplyTo('[email protected]', 'First Last');

//Set who the message is to be sent to
$mail->addAddress('[email protected]', 'John Doe');

//Set the subject line
$mail->Subject = 'PHPMailer GMail SMTP test';

//Read an HTML message body from an external file, convert referenced images to embedded,
//convert HTML into a basic plain-text alternative body
$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));

//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';

//Attach an image file
$mail->addAttachment('images/phpmailer_mini.png');

//send the message, check for errors
if (!$mail->send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message sent!";
}

Hi,
Do you have any custom firewall rules or applications that could block that port? If yes then try to disable it.

The option: whm > security center > SMTP Restrictions is Disable.

Hello,

Are you also using the CSF firewall? If so, check to see if the "SMTP_BLOCK" setting is enabled.

Thank you.
