Validation/DNSCheckValidation.php goes wrong if no MX record

[AlexQwamp]

Hello,

Looking at

EmailValidator/src/Validation/DNSCheckValidation.php

Line 171 in 5153460

foreach ($dnsRecords as $dnsRecord) {

and

EmailValidator/src/Validation/DNSCheckValidation.php

Line 197 in 5153460

if ($dnsRecord['type'] !== 'MX') {

condition " if (empty($this->mxRecords))" can never been achieved when DNSRecord contains no MX.

By consequence, if you test a domain with no MX record at all, validation returns valid.
