I doubt whether this condition is properly built.

Lines 115 to 116 in 793f336

    
           $heloDomain = $environment->getHeloDomain(); 
        
           if ($heloDomain === '' || strcasecmp($heloDomain, $environment->getMailFromDomain()) !== 0) {

strcasecmp('s2.yetiforce.com', 'xxyr.com') = -5

'xxyr.com' is a fictional domain

Example:

$environment = new \SPFLib\Check\Environment('54.38.127.118', 's2.yetiforce.com', 'test@xxyr.com');
$checker = new \SPFLib\Checker();
$checkResult = $checker->check($environment);

	$heloDomain = $environment->getHeloDomain();
	if ($heloDomain === '' \|\| strcasecmp($heloDomain, $environment->getMailFromDomain()) !== 0) {

Doubt whether the condition is correct
