README

A custom Laravel mail transport driver to send emails via the Postal mail server using its HTTP API instead of SMTP. Official documentation: https://apiv1.postalserver.io/controllers/send/message.html

📦 Features

• Send transactional emails via Postal HTTP API
• Uses Laravel's native Mail::to()->send() interface
• Clean, framework-native mail transport driver
• Compatible with Laravel version 8.0+

🚀 Installation

Step 1: Require the package (from local path or Git)

If using local development:

composer require php-monsters/laravel-postal-driver

Or add to your composer.json:

"repositories": [
  {
    "type": "path",
    "url": "./packages/PhpMonsters/LaravelPostalDriver"
  }
],
"require": {
  "php-monsters/laravel-postal-driver": "*"
}

Then run:

composer update

⚙️ Configuration

Step 2: Set up .env variables

MAIL_DRIVER=postal
POSTAL_API_KEY=your_postal_api_key_here
POSTAL_API_ENDPOINT=https://postal.yourdomain.com

Step 3: Configure config/mail.php

Add to the mailers array:

'mailers' => [
    'postal' => [
        'transport' => 'postal',
        'key' => env('POSTAL_API_KEY'),
        'endpoint' => env('POSTAL_API_ENDPOINT'),
    ],
],

✉️ Usage

Use Laravel's standard Mail facade:

use App\Mail\TestMail;
use Illuminate\Support\Facades\Mail;

Mail::to('recipient@example.com')->send(new TestMail());

Your Mailable class should work as usual.

📐 Under the Hood

This driver makes HTTP POST requests to:

POST /api/v1/send/message

With headers:

X-Server-API-Key: {your_api_key}
Content-Type: application/json

Payload:

{
  "to": "recipient@example.com",
  "from": "you@yourdomain.com",
  "subject": "Subject Line",
  "plain_body": "Text version",
  "html_body": "<p>HTML version</p>"
}

🛠 Requirements

• Laravel 8 or newer
• Postal mail server with API access
