MAIL_DRIVER=smtp
MAIL_HOST=null
MAIL_PORT=null
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

MAIL_FROM_ADDRESS = 'hello@example.com'

AWS_SECRET_ACCESS_KEY= secret_access_key  //create user or in existing user check secret key
AWS_DEFAULT_REGION=eu-west-1  //change with your region
AWS_BUCKET=

       'secret' => env('AWS_SECRET_ACCESS_KEY'),
       'region' => env('AWS_DEFAULT_REGION', 'eu-west-1'), // change with your region
