note 20765 added to function.getmxrr

I ran into a DNS in Canada that has no MX records, and there are probably others. Even though incorrect, it has to be handled. The default is to assume the mail server is at the same domain. For example: if (!checkdnsrr($domain, 'MX') || !getmxrr($domain, $mxhosts, $weight)) $mxhosts = array($domain); -- http://www.php.net/manual/en/function.getmxrr.php http://master.php.net/manage/user-notes.php?action=edit+20765 http://master.php.net/manage/user-notes.php?action=delete+20765 http://master.php.net/manage/user-notes.php?action=reject+20765
