DNSCheckValidation returning valid true for email "0"

[nizamani]

Class Egulias\EmailValidator\Validation\DNSCheckValidation is returning email "0" as valid email, for some reason DNS check is passing when email is "0", I perform validation check using following code:

$isEmailValid = $dnsCheckValidation->isValid($email, new EmailLexer());

In above example $isEmailValid is returned as true and "0" becomes a valid email address.

Egulias\EmailValidator\Validation\DNSCheckValidation isValid() also returns true for these email addresses:
new.email
email.com

Fixed in v3.
Can you please confirm that this still fails in latest v2 (2.1.25)?

Tested, should be fixed in 2.1.25.
