Send Laravel mail through an API

Register the mailer as agentisend. The transport posts each message to POST /emails. A refusal throws an exception whose fix is the API's fix field.

composer require agentisend/laravel

'mailers' => [
    'agentisend' => [
        'transport' => 'agentisend',
    ],
],

MAIL_MAILER=agentisend
AGENTISEND_API_KEY=as_your_key

The Symfony DSN and the field map are on the guide: https://agentisend.com/docs/guides/laravel#the-mail-driver
