Re: [PHP] validating email address

Quick note: The PEAR Validate package does this for you. It also checks 
for an alternate A record.

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;
       }
   }
}
