In this particular situation they can give A, A6 or AAAA documents. To make it possible for Zend \ Validator \ EmailAddress to check additionally for these various other reports, you need to prepare deep MX recognition. This can be performed at commencement by preparing the deep alternative or by utilizing setOptions()

Sometimes it may be beneficial to acquire the server’ s MX information whichhave actually been made use of to perform further processing. Just utilize getMXRecord() after verification. This technique comes back the acquired MX report featuring body weight and arranged throughit.
