Laravel Certificate Verification Errors When Sending Tls Email

Laravel certificate verification errors when sending TLS email

Solution:

1. Download the cURL cacert.pem file

2. Put the cacert.pem somewhere you like

3. Edit php.ini to reference this file location:

curl.cainfo = D:/Servers/php/sslfiles/cacert.pem
openssl.cafile = D:/Servers/php/sslfiles/cacert.pem

4. Restart the web server

laravel shows error when sending email using tls and my own postfix/virtualmin server

I figured it out the problem.

My virtualmin/postfix setup was missing the CA certificiation, and since i used letsencrypt for ssl, i had to put the path of generated CA in the config.

Here : Webmin --> Servers ---> PostFix Mail Server ----> Smtp authentication and encryption.

Configure email with TLS in Laravel - Error SSL operation failed with code 1

Finally when I change the MAIL_ENCRYPTION to null, it worked just fine. I assume that is a server configuration problem, I'll check it with the sysadmin.

How to deal with self-signed TLS certificates in Laravel's SMTP driver?

Well in that link you provided the solution is straight-forward.

The correct solution is to fix your SSL config - it's not PHP's fault!

how to fix it? in config/mail.php ,'driver' => env('MAIL_DRIVER', 'smtp'), should be 'driver' => env('MAIL_DRIVER', 'mail'), (credits: Danyal Sandeelo)

LARAVEL 9. ERROR LARAVEL EMAIL: Unable to connect with STARTTLS: stream_socket_enable_crypto(): SSL operation failed with code 1

I had this problem after upgrading to the new 9 version, so you need to follow two steps.

1. Edit your .env file located in the root of the project The place where your mail settings are described, change tls to null. If you do not have such a line, then add

   MAIL_ENCRYPTION=null

2. If you have version 8 then this will be enough, but in version Laravel 9 you will need to open the file app/config/mail.php Find a section mailers smtp add two options 'auth_mode' => null and 'verify_peer' => false an example of how it would look

   '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,
   
   
                'auth_mode'  => null,
                'verify_peer'       => false,
            ],
   

Laravel 5.5: Can't sent email via google (SSL operation failed)

Editor's note: disabling SSL verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint such as Gmail, and you'll be vulnerable to a Man-in-the-Middle Attack.

Be sure you fully understand the security issues before using this as a solution.

You must disable signing the letter with a certificate in config mail file: mail.php

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