Local EmailAdress Validator Problems (Windows)

[michalbundyra]

Hey there!

If i attach following validator to my validator chain and validate emails like [email protected] or [email protected] or simply my own domain i will get the Validator\EmailAddress::INVALID_SEGMENT message printed.

new Validator\EmailAddress(
    [
        'useDeepMxCheck' => true,
        'useDomainCheck' => true,
        'useMxCheck'     => true
    ]
)

I debugged the code and found out that the call of $result = getmxrr($this->idnToAscii($this->hostname), $mxHosts, $weight); in method validateMXRecords() will return true but the $mxHosts and $weight is empty. Thats why the isValid() return false. I tested it under Windows, linux and Macintosh. Linux and Macintosh works great but Windows fails.

I tried to use $result = dns_get_record($this->idnToAscii($this->hostname), DNS_MX, $mxHosts, $weight); instead but then my php-cgi quits.

Linux/Macintosh:

php -r '$mxHosts = [];$weight  = [];$result = getmxrr("googlemail.com", $mxHosts, $weight);var_dump($result, $mxHosts, $weight);'
bool(true)
array(5) {
  [0]=>
  string(31) "alt1.gmail-smtp-in.l.google.com"
  [1]=>
  string(31) "alt4.gmail-smtp-in.l.google.com"
  [2]=>
  string(31) "alt3.gmail-smtp-in.l.google.com"
  [3]=>
  string(31) "alt2.gmail-smtp-in.l.google.com"
  [4]=>
  string(26) "gmail-smtp-in.l.google.com"
}
array(5) {
  [0]=>
  int(10)
  [1]=>
  int(40)
  [2]=>
  int(30)
  [3]=>
  int(20)
  [4]=>
  int(5)
}

Windows:

php -r '$mxHosts = [];$weight  = [];$result = getmxrr("googlemail.com", $mxHosts, $weight);var_dump($result, $mxHosts, $weight);'
bool(true)
array(0) {
}
array(0) {
}

A litle search in php documention we see that a following note:

The question is this, the validation should care about platform that is running and then show some warning that requires the installation of Net_DNS?

One possible solution is:

if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
    // do something here!
}
