You could use MX records if you wanted to. I found this some time ago... function checkEmail($Email) { //Do the basic Reg Exp Matching for simple validation if (eregi("[EMAIL PROTECTED]", $Email)) { return FALSE; }
//split the Email Up for Server validation list($Username, $Domain) = split("@",$Email); //If you get an mx record then this is a valid email domain if(getmxrr($Domain, $MXHost)) { return TRUE; } else { //else use the domain given to try and connect on port 25 //if you can connect then it's a valid domain and that's good enough if(fsockopen($Domain, 25, $errno, $errstr, 30)) { return TRUE; } else { return FALSE; } } } ----- Original Message ----- From: "Blake Schroeder" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, December 04, 2003 2:31 AM Subject: [PHP] validating email address Whats the best way to validate email address (check for white space, check for .com, .net.edu etc) -Blake -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
