[QUOTE="sensaze, post: 399990, member: 73918"] So lets say from a security point of view, I don't want my server IP leaking, so other than actually checking that [email]hello@email.com[/email] does actually exist all I would have to do is (correct me if im wrong). Create a new php file in my includes folder called emailcheck.php with this script: [PHP]function myCheckDNSRR($hostName, $recType = '') { if(!empty($hostName)) { if( $recType == '' ) $recType = "MX"; exec("nslookup -type=$recType $hostName", $result); // check each line to find the one that starts with the host // name. If it exists then the function succeeded. foreach ($result as $line) { if(eregi("^$hostName",$line)) { return true; } } // otherwise there was no mail handler for the domain return false; } return false; }[/PHP] and then edit say my register.php page at the top with something like: [PHP]<?php include_once 'includes/emailcheck.php'; ?>[/PHP] [doublepost=1487345637,1487345603][/doublepost] That is already configured correctly, I'm trying to ensure people actually sign up with a valid/working email address.
