Description:
------------
On a server with support for IPv4 and IPv6, whereas the target domains support both protocols, the fsockopen function only works with IPv4, causing timeout when try to connect via IPv6.

Test script:
---------------
$con = fsockopen('mx.mydomain.com', 587, $errno, $errstr, 10);
if(empty($con)) echo "Not connected: ".$errno." - ".$errstr;
else echo "Connected!";

Expected result:
----------------
Connected!

Actual result:
--------------
Not connected: 110 - Connection timed out

So you can connect to it, from the same server, to the same server and the same port, all over IPv6, using other applications (like telnet) but not with PHP?
