Does Nette Enable TLS Encryption?

blsn

Hi,

I use Nette Mail: Sending E-mails, in my Slim 3 application.
https://github.com/nette/mail

I use the following setting to send an email on my local server (Xampp).

$app = new \Slim\App([
	'settings' => [
		'displayErrorDetails' => true,
		'mailer' => [
		    'host' => 'smtp.gmail.com',
            'username' => 'myname@gmail.com',
            'password' => 'mypassword',
			'secure' => 'tls'
		],
	],
]);

I get the following error message:

Slim Application Error
The application could not run because of the following error:

Hello there,

it might be a problem with the port: SmtpMailer apparently defaults to 465 for ssl and 25 for anything else, while Google runs the Gmail SMTP server on 587 for TLS. Try adding 'port' => 587 to the config.

Thank you for your reply,
'port' => 587 was added, still not work.

Check if you have this port opened on your PC / Router if its from local. You may be behind firewall.

SOLVED:

Messed up TLS certificates intercepting SMTP traffic ..
needed to skip certificate validation checks when I run the code locally on my computer:

$app = new \Slim\App([
	'settings' => [
		'displayErrorDetails' => true,
		'mailer' => [
		    'host' 		=> getenv('MAIL_HOST'),
            'username' 	=> getenv('MAIL_USERNAME'),
            'password' 	=> getenv('MAIL_PASSWORD'),
			'secure' 	=> getenv('MAIL_ENCRYPTION'),
			'port' 		=> getenv('MAIL_PORT'),

			'context' =>  [
				'ssl' => [
					'verify_peer' => false,
					'verify_peer_name' => false,
					'allow_self_signed' => true
				]
			],

		],
		'baseUrl' => getenv('BASE_URL')
	],
]);
