Installation

You can install the package via Composer:

The package will automatically register its service provider and facade.

Configuration

You can publish the config file with:

php artisan vendor:publish --tag="laravel-spamassassin-score-config"

This is the contents of the published config file:

return [
    'api' => 'https://spamcheck.postmarkapp.com/filter',

    // Default "long". Must either be "long" for a full report of processing rules, or "short" for a score request.
    'option' => 'long'
];

Configuration Options

• api: The SpamAssassin API endpoint URL
• option: The report format - either "long" for a full report of processing rules, or "short" for a score request only

Usage

Using the Facade

use palPalani\SpamassassinScore\Facades\SpamassassinScore;

// Get spam score with default configuration
$result = SpamassassinScore::getScore($emailContent);

// The result will contain:
// - 'score': The spam score
// - 'success': Whether the check was successful
// Additional fields when using 'long' option format

Using Dependency Injection

use palPalani\SpamassassinScore\SpamassassinScore;

class EmailController extends Controller
{
    public function __construct(
        private SpamassassinScore $spamassassinScore
    ) {}

    public function checkEmail(Request $request)
    {
        $result = $this->spamassassinScore->getScore($request->input('email'));
        
        if ($result['score'] > 5.0) {
            return response()->json(['message' => 'Email may be spam'], 400);
        }
        
        // Proceed with sending email
    }
}

Using Direct Instantiation

use palPalani\SpamassassinScore\SpamassassinScore;

$spamassassinScore = new SpamassassinScore();
$result = $spamassassinScore->getScore($emailContent);

// Access the score
$score = $result['score'] ?? null;

Example Response

When using the default "long" option, the response includes:

[
    'success' => true,
    'score' => 2.5,
    'rules' => [
        // Full list of rules that matched
    ],
    'description' => '...'
]

When using "short" option, the response is:

[
    'success' => true,
    'score' => 2.5
]
