Swiftmailer / Mailhog

[shaneparsons]

Info:

• Docker version: 19.03.2
• Laradock commit: cb910c590e00cee77ebbf75867aae0c7d0199119
• System info: macOS
• System info disto/version: 10.14.4

Issue:

---

Perhaps related to #2039, ever since I switched a project from Homestead to Laradock, I havn't been able to send emails... Is the issue perhaps with Swiftmailer? Is Swiftmailer included with Laradock?

Exception:

Swift_TransportException: Connection could not be established with host localhost [Cannot assign requested address #99] in /var/www/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:269

Expected behavior:

---

Emails to send, like they were in Homestead.

Reproduce:

---

Try sending an email (feel free to use my code below). The exception I got was through Horizon.

Relevant Code:

.env

QUEUE_CONNECTION=redis
REDIS_HOST=redis
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=smtp
MAIL_HOST=mailhog
MAIL_PORT=1025
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAIL_FROM_ADDRESS=notifications@laravel.test
MAIL_FROM_NAME=Laravel

    public function build()
    {
        return $this->from(env('MAIL_FROM_ADDRESS'), env('MAIL_FROM_NAME'))

            ->markdown('emails.test');
    }

# Test

This is a test.
@endcomponent

Hmm, it seems to work now after running docker-compose restart...

The only thing I can think of is perhaps my change from MAIL_HOST=localhost to MAIL_HOST=mailhog hadn't fully registered and the restart fixed it.
