Laravel - Disable SSL verification for SMTP

Laravel - Disable SSL verification for SMTP.php

<?php 
// File :: config/mail.php

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

In case you are using Laravel 7.0 you can disable SSL verification in SwiftMailer this way (please note that disabling SSL verification is not recommended!):

config/mail.php

'mailers' => [
    'smtp' => [
        'transport' => 'smtp',
        'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
        'port' => env('MAIL_PORT', 587),
        'encryption' => env('MAIL_ENCRYPTION', 'tls'),
        'username' => env('MAIL_USERNAME'),
        'password' => env('MAIL_PASSWORD'),
        'timeout' => null,
        'stream' => [
            'ssl' => [
                'allow_self_signed' => true,
                'verify_peer' => false,
                'verify_peer_name' => false,
            ],
        ],
    ],
],

Hi maciej-laskowski , I was facing same issues but after doing this I am getting another error
#message: """
Failed to authenticate on SMTP server with username "support@helpknx.com" using 2 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code "535", with message "535 Incorrect authentication data ◀
". Authenticator PLAIN returned Expected response code 235 but got code "535", with message "535 Incorrect authentication data
".
"""

@jennyp786 The error message you are receiving now regards a different problem. I would suggest you start with double checking your smtp credentials using an email client for example. Also, if you provide your SMTP password in .env file make sure it is enclosed in quotes.

Thanks , I just reset the password and config cache clear , I got solution

It's not working fine for me on Laravel 7.4

@AtakanATC if you are looking for help provide more details. Which mailer are you using? what have you already tried? what is the exact error message that you are getting?
