Usage

Basic Validation

use KolayBi\Validation\Mail\MailChecker;
use KolayBi\Validation\Mail\Exceptions\AbstractMailException;

try {
    MailChecker::check('user@example.com');
    // Email is valid
} catch (AbstractMailException $e) {
    // Handle specific validation errors
    echo $e->getMessage();
}

Simplified Boolean Check

if (MailChecker::isValid('user@example.com')) {
    // Email is valid
} else {
    // Email is invalid
}

Skip External Validation

// Perform only local validation checks
MailChecker::check('user@example.com', skipExternalControl: true);

// Perform only local validation checks
if (MailChecker::isValid('user@example.com', skipExternalControl: true)) {
    // Email is valid
} else {
    // Email is invalid
}

Advanced Validation Methods

The package provides granular validation methods for specific checks:

// Check individual validation aspects
if (MailChecker::isWhitelisted('user@example.com')) {
    // Email domain is in whitelist - trusted domain
}

if (MailChecker::isBlacklisted('user@example.com')) {
    // Email domain is explicitly blocked
}

if (MailChecker::isDisposable('user@example.com')) {
    // Email is from a temporary/disposable email provider
}

if (MailChecker::isValidFormat('user@example.com')) {
    // Email format passes validation checks
}

// Inverse methods for negative checks
if (MailChecker::isNotWhitelisted('user@example.com')) {
    // Email requires validation (not in trusted whitelist)
}

if (MailChecker::isNotBlacklisted('user@example.com')) {
    // Email is not explicitly blocked
}

if (MailChecker::isNotDisposable('user@example.com')) {
    // Email is from a permanent email provider
}

if (MailChecker::isInvalidFormat('user@example.com')) {
    // Email format is invalid
}

Exception Types

The package throws specific exceptions for different validation scenarios:

• EmptyMailException - Email address is empty
• InvalidMailException - Email format is invalid
• BlacklistedMailException - Domain is blacklisted
• DisposableMailException - Domain is from a disposable email provider
• InaccessibleMailException - Failed external validation
• ExternalMailProviderException - External validation error
