Installation

You can install the package via composer:

composer require martian/spammailchecker

MartianSpamMailCheckerSpamMailCheckerServiceProvider::class,

If you are going to be using the facade, you'll need to register it as well. Open config/app.php and add the following line to the aliases array:

'SpamMailChecker' => MartianSpamMailCheckerFacadesSpamMailChecker::class,

Publish Configuration File

Publish the configuration file using the following command:

php artisan vendor:publish --provider="MartianSpamMailCheckerProvidersSpamMailCheckerServiceProvider"

Configuration

The configuration file is located at config/laravel-spammail-checker.php. You may configure the package to use any of the supported drivers. The default driver is local which uses a local text list of spam email domains.

Local Driver Configuration

In order to use localas your driver of choice, you need to set the default key in the config/laravel-spammail-checker.php configuration file to local:
```
    'default' => 'local',
```
Or you can set the SPAM_MAIL_CHECKER_DEFAULT_DRIVER environment variable to local in your .env file.
```
    SPAM_MAIL_CHECKER_DEFAULT_DRIVER=local
```

The local driver uses a local text list of spam email domains. The file is located at resources/config/emails.txt. You can include more domains by adding them to the blacklist array or exclude domains by adding them to the whitelist array.

    'drivers' => [
        'local' => [
            ...
            'whitelist' => [
                // Add domains you want the local driver to ignore here
                'gmail.com',
                'yahoo.com',
            ],
            'blacklist' => [
                // Add domains you want the local driver to validate against here
                'mailinator.com',
                'spam.com',
            ],
        ]
    ]

Clear the config and cache using the following commands after making changes to the configuration file:
```
    php artisan optimize:clear
```

NOTE: The local driver is case-insensitive. So, you don't need to worry about the case of the email domain.

Remote Driver Configuration

In order to use remote as your driver of choice, you need to set the default key in the config/laravel-spammail-checker.php configuration file to remote:
```
    'driver' => 'remote',
```
Or you can set the SPAM_MAIL_CHECKER_DEFAULT_DRIVER environment variable to remote in your .env file.
```
    SPAM_MAIL_CHECKER_DEFAULT_DRIVER=remote
```

The remote driver uses PHP In-built functions getmxrr(), checkdnsrr(). fsockopen() to validate email domain. You can configure the remote driver on whether to check for MX - getmxrr(), DNS - checkdnsrr(), and SMTP -fsockopen or validate email domain. You can also configure the timeout value in seconds.

    'drivers' => [
        ...
        'remote' => [
            ...
            'check_dns' => true, // When set to true, it will check for DNS
            'check_smtp' => false, // When set to true, it will check for SMTP
            'check_mx' => false, // When set to true, it will check for MX record
            'timeout' => 60 * 5, // 5 minutes
        ]
    ]

AbstractApi Driver Configuration

In order to use abstractapi as your driver of choice, you need to set the default key in the config/laravel-spammail-checker.php configuration file to abstractapi:
```
    'default' => 'abstractapi',
```
Or you can set the SPAM_MAIL_CHECKER_DEFAULT_DRIVER environment variable to abstractapi in your .env file.
```
    SPAM_MAIL_CHECKER_DEFAULT_DRIVER=abstractapi
```
Add your ABSTRACTAPI_API_KEY AbstractAPI key you got from here to your env file.
```
ABSTRACTAPI_API_KEY=abstractapi_api_key
```

You can configure the score to determine the threshold for a valid email address. The score ranges from 0 to 1. The higher the score, the more likely the email address is valid. You can also accept disposable email addresses by setting accept_disposable to true.

    'drivers' => [
        ...
        'abstractapi' => [
            ...
            'score' => 0.5, // 0.5 is the default score
            'accept_disposable_email' => true // When set to true, it will accept disposable email addresses
        ]
    ]

QuickEmailVerification Driver Configuration

In order to use quickemailverification as your driver of choice, you need to set the default key in the config/laravel-spammail-checker.php configuration file to quickemailverification:

        ]
    ]
```

Usage

In order to use the package, you need to call the spammail validation rule in your validation rules. You can also change the rule name to whatever you want in the config/laravel-spammail-checker.php configuration file under the rule key, likewise the error message under the error_message key.

/**
 * Get a validator for an incoming registration request.
 *
 * @param  array  $data
 * @return IlluminateContractsValidationValidator
 */
protected function validator(array $data)
{
    return Validator::make($data, [
        'email' => 'required|spammail|max:255',
    ]);
}

Or make use of spammail in your Requests file like this:

 /**
 * Get the validation rules that apply to the request.
 *
 * @return array
 */
public function rules()
{
    return [
        'email' => 'required|spammail|max:255',
    ];
}

Adding Custom Error Message

A custom error message can be added to the spammail validation rule.

    'email.spammail' => 'This email address is invalid.', // Custom error message

Or you can change the error message in the config/laravel-spammail-checker.php configuration file under the error_message key.

    'error_message' => 'This email address is invalid.', // Custom error message

Using Classes Directly

You can also use the classes directly without using the spammail validation rule. This is useful when you want to use the package in your own custom validation rule or your own custom class.

use MartianSpamMailCheckerSpamMailChecker;

public function checkEmail($email)
{
    $spamMailChecker = new SpamMailChecker();
    $spamMailChecker->validate($email);
}

Using Facade

You can also use the SpamMailChecker class directly without instantiating it.

use MartianSpamMailCheckerFacadesSpamMailChecker;

public function checkEmail($email)
{
    SpamMailChecker::validate($email);
}

Using Each Driver Individually

You can also use each driver individually without using the spammail validation rule. This is useful when a certain driver is needed in a particular situation.

Using VerifaliaDriver

use MartianSpamMailCheckerDriversVerifaliaDriver;

public function checkEmail($email)
{
    $verifaliaDriver = new VerifaliaDriver();
    $verifaliaDriver->validate($email);
}

Using SendGridDriver

use MartianSpamMailCheckerDriversSendGridDriver;

public function checkEmail($email)
{
    $sendGridDriver = new SendGridDriver();
    $sendGridDriver->validate($email);
}

Using AbstractApiDriver

use MartianSpamMailCheckerDriversAbstractApiDriver;

public function checkEmail($email)
{
    $abstractApiDriver = new AbstractApiDriver();
    $abstractApiDriver->validate($email);
}

Using RemoteDriver

use MartianSpamMailCheckerDriversRemoteDriver;

public function checkEmail($email)
{
    $remoteDriver = new RemoteDriver();
    $remoteDriver->validate($email);
}

Using LocalDriver

use MartianSpamMailCheckerDriversLocalDriver;

public function checkEmail($email)
{
    $localDriver = new LocalDriver();
    $localDriver->validate($email);
}

Using QuickEmailVerificationDriver

use MartianSpamMailCheckerDriversQuickEmailVerificationDriver;

public function checkEmail($email)
{
    $quickEmailVerificationDriver = new QuickEmailVerificationDriver();
    $quickEmailVerificationDriver->validate($email);
}
