Greetings to the community!

I have recently developed a web page with Laravel 9.X, which works correctly in local, but when I upload it to my Host, I am having problems with sending emails.

When I have been testing locally, it has been working correctly, and I have been using mailtrap. Now that I have uploaded it to the server, I have my own SMTP, and it is not working for me. I have the ssl certificate created, but there is no way it will send me any mail. I get the following error:

Unable to connect with STARTTLS: stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed.

SSL working fine when i visit the site with https.

I have configured my .env file, where I have put:

HOST: my smtp server; PORT: 587; ENCRYPTION TYPE: SSL; USERNAME AND PASSWORD: Those of my email account.

I have been touching also my file located in config/mail.php, putting the same configuration as in the .env file. I have also tried with other ports like 25, 465... among others.

I have tried to access the mail account from outlook, using the IMAP protocol, and I have been able to connect correctly, so the mail can be accessed.

I have checked lot of things in Google, and also every blogs y found in Stack Overflow, but nothing worked.

Any idea what is going on? Am I missing something to configure?

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,
         ],
