About The Project

Flexible and simple library for checking email addresses. Usual framework validators are usually checking email correctness, but this library is implementing other kind of validation.

It can check is mail:

• registered in mail provider from forbidden country;
• registered in forbidden domain (all possible levels);
• used for spam or scam (dangerous), temporary, had suspicious behaviour, is registered on paid or public (like gmail) mail provider.

Of course, you can always propose new domains to add into listed in the "data" directory.

Key feautures:

• fast search - binary search in the pre-sorted dictionaries (in comparison with other popular libraries with linear search)
• flexible configurations - not only one strict list
• low memory usage - disctionaries are not loaded fully into memory (as in other popular libraries)
• frequent updates
• easy collaboration
• large disctionary- 60k+ of domains (not only public email providers) in the dictionary

Usage

This table will help to understand possible usage of library and all default values:

Here you will find different cases of usage.

Checking that mail address registered in Russian mail provider:

use Coodde\LaravelMailChecker\Rules\MailRegionsValidation;
use Coodde\LaravelMailChecker\Regions;

public function store(Request $request): RedirectResponse
{
    $validated = $request->validate([
        'email' => ['required', new MailRegionsValidation([Regions::RUSSIA])],
    ]);
 
    // OR with configs from env, ex. (country code) - MAIL_CHECKER_REGIONS=ru

    $validated = $request->validate([
        'email' => ['required', new MailRegionsValidation()],
    ]);
 
    // Request is valid...
 
    return redirect('/list');
}

Checking that mail address registered in "ru" or "mail.by" domains:

use Coodde\LaravelMailChecker\Rules\MailDomainsValidation;
use Coodde\LaravelMailChecker\Regions;

public function store(Request $request): RedirectResponse
{
    $validated = $request->validate([
        'email' => ['required', new MailDomainsValidation(['ru', 'mail.by'])],
    ]);
 
    // OR with configs from env, ex. - MAIL_CHECKER_DOMAINS=ru,mail.by

    $validated = $request->validate([
        'email' => ['required', new MailDomainsValidation()],
    ]);

    // Request is valid...
 
    return redirect('/list');
}

Checking that mail address is placed in dangerous or suspicious lists:

use Coodde\LaravelMailChecker\Rules\MailListedValidation;
use Coodde\LaravelMailChecker\Regions;

public function store(Request $request): RedirectResponse
{
    $validated = $request->validate([
        'email' => ['required', new MailListedValidation([MailListedValidation::CATEGORY_DANGEROUS, MailListedValidation::CATEGORY_SUSPICIOUS])],
    ]);

    // OR with configs from env, ex. - MAIL_CHECKER_CATEGORIES=dangerous,suspicious

    $validated = $request->validate([
        'email' => ['required', new MailListedValidation()],
    ]);
 
    // Request is valid...
 
    return redirect('/list');
}

Complex validation to allow only corporate emails, :

use Coodde\LaravelMailChecker\Rules\MailValidation;
use Coodde\LaravelMailChecker\Regions;

public function store(Request $request): RedirectResponse
{
    $validated = $request->validate([
        'email' => [
        	'required',
        	new MailValidation(
        		[
        			MailListedValidation::CATEGORY_DANGEROUS,
        			MailListedValidation::CATEGORY_SUSPICIOUS,
        			MailListedValidation::CATEGORY_TEMPORARY,
        			MailListedValidation::CATEGORY_PAID,
        			MailListedValidation::CATEGORY_PUBLIC,
        		],
        		[
        			'fb.com',
        		],
        		[
        			Regions::RUSSIA,
        			Regions::BELARUS,
        		],
        	),
       	],
    ]);

    // OR with separate validators

    $validated = $request->validate([
        'email' => [
        	'required',
        	new MailListedValidation([
    			MailListedValidation::CATEGORY_DANGEROUS,
    			MailListedValidation::CATEGORY_SUSPICIOUS,
    			MailListedValidation::CATEGORY_TEMPORARY,
    			MailListedValidation::CATEGORY_PAID,
    			MailListedValidation::CATEGORY_PUBLIC,
        	]),
        	new MailDomainsValidation([
    			'fb.com',
    		]),
        	new MailRegionsValidation([
    			Regions::RUSSIA,
    			Regions::BELARUS,
    		]),
       	],
    ]);
 
    // Request is valid...
 
    return redirect('/list');
}

Of course you can combine restrictioned domains, countries, and categories

Roadmap

• Checking by countries
• Checking by domains
• Prepared lists
  • Dangerous - usually scaming servers / domains
  • Suspicios - usually spaming servers / domains
  • Paid - mail providers with non-free subscription
  • Temporary - services for mails which will be removed soon after creation
  • Public - popular free services like gmail, outlook, etc
• Checking by prepaired lists
  • From files - it uses binary search without file content buffering
  • From cache - cache files with lists compiled into php file
  • From memory - storing lists in memcache
  • From database - by using PDO library+
