Sending mail probably is one of the inseparable functionality when an app has registered or subscribed users. During development, we tend to use an SMTP testing server like mailtrap.io
.
Mailtrap provides a free
plan for a single inbox for testing and we can send mails to this inbox with a limitation of emails stored in the inbox. Somehow when we use this free plan, we also come to a limitation of how many emails can be sent within a second(s), so we can't send multiple emails at the same time and we have to make a delay/sleep for each mail process.
The answer to the above problems is mailhog
. Mailhog is an SMTP testing server that runs locally in your server/machine, and Laradock has this service. Let's try this out.
Run Mailhog server and the web UI
I assume you have tried and know how to work with Laradock, if not then you can start to setup a laravel app with Laradock here.
To run the mailhog server and the web UI, simply run this docker-compose
command:
docker-compose up -d mailhog
the container should be working and status should be up
when you check it using docker-compose ps
command:
Name Command State Ports
---------------------------------------------------------------------------------------------------------------------
laradock_mailhog_1 MailHog Mailhog Up 0.0.0.0:1025->1025/tcp, 0.0.0.0:8025->8025/tcp
Setup Mailhog for Laravel App
in your laravel app's .env
, add/change these parameters into like this:
MAIL_DRIVER=smtp
MAIL_HOST=mailhog
MAIL_PORT=1025
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAIL_FROM_ADDRESS=from@example.com
MAIL_FROM_NAME=Example
Example of sending mail in Laravel
We can create a simple artisan command to send mail, here are what you need to add to your laravel project:
app\Console\Commands\ExampleSendMailCommand.php
:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use App\Mail\ExampleMail;
use Illuminate\Support\Facades\Mail;
class ExampleSendMailCommand extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'example:send-mail';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Command for exemplify the mail sending in laravel';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
Mail::to('example@mailinator.net')->send(new ExampleMail());
}
}
app\Mail\ExampleMail.php
:
<?php
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
class ExampleMail extends Mailable implements ShouldQueue
{
use Queueable, SerializesModels;
/**
* Create a new message instance.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Build the message.
*
* @return $this
*/
public function build()
{
return $this->view('mails.example');
}
}
resources\views\mails\example.blade.php
:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Example Mail Test</title>
</head>
<body>
<h1>Hello from the other side!</h1>
</body>
</html>
add/register the command to app\Console\Kernel.php
:
<?php
namespace App\Console;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
use App\Console\Commands\ExampleSendMailCommand;
class Kernel extends ConsoleKernel
{
/**
* The Artisan commands provided by your application.
*
* @var array
*/
protected $commands = [
ExampleSendMailCommand::class,
];
/**
* Define the application's command schedule.
*
* @param \Illuminate\Console\Scheduling\Schedule $schedule
* @return void
*/
protected function schedule(Schedule $schedule)
{
// $schedule->command('inspire')
// ->hourly();
}
/**
* Register the commands for the application.
*
* @return void
*/
protected function commands()
{
$this->load(__DIR__.'/Commands');
require base_path('routes/console.php');
}
}
Finally, now enter the laradock workspace bash (if you haven't) using your favorite CLI to execute this command:
docker-compose exec --user=laradock workspace bash
go inside your laravel app root directory and execute this artisan command:
php artisan example:send-mail
If there is no error when executing the command, then let's see our inbox!
Acessing the Mailhog Web UI
The mailhog web UI should be accessible at http://localhost:8025. Your example email should be there :)
Making email messages persistent
Mailhog store the caught
messages in memory, which means when you stop container and then run again, all your messages will be gone (forever). So if you want to keep them, then you have to make it persistent by configuring the laradock/docker-compose.yml
. Find the mailhog configuration in the file, and change it into like this:
...
## Mailhog ################################################
mailhog:
build: ./mailhog
volumes:
- ${DATA_PATH_HOST}/mailhog/maildir:/maildir
command: ["-storage=maildir", "-maildir-path=/maildir"]
ports:
- "1025:1025"
- "8025:8025"
networks:
- frontend
- backend
...
Then restart or stop-run the container. Starting from this point, all your messages will be saved.
Have fun exploring Mailhog in Laradock!
laravel version used: 6.0 LTS

Hi, thanks for share. Do you know how send emails from Laradock-laravel in production?
laravel.com/docs/8.x/mail#driver-p...
A lot of choices for your production like Mailgun and AWS SES. Or you can using Gmail SMTP.
