I have a question. if someone could go thru the code and verify that I have not got anything wrong.
some user verifications pass when they should not be passing.
functionz.php
function SnowCheckMail($Email,$Debug=true)

global $HTTP_HOST;
$Return =array();
if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $Email)) {
$Return[0]=false;
$Return[1]="${Email} is not in the correct email format.";
return $Return;
}
else
list ( $Username, $Domain ) = split ("@",$Email);
if ( checkdnsrr ( $Domain, "MX" ) ) {
if($Debug) echo "Confirmation : MX record for {$Domain} exists.<br>";
if ( getmxrr ($Domain, $MXHost)) {
if($Debug) {
echo "Confirmation : by MX LOOKUP.<br>";
for ( $i = 0,$j = 1; $i < count ( $MXHost ); $i++,$j++ ) {
echo " Result($j) - $MXHost[$i]<BR>";
}
}
}
$ConnectAddress = $MXHost[0];
}
else {
$ConnectAddress = $Domain;
}
$Connect = fsockopen ( $ConnectAddress, 25 );
if ($Connect)

fputs ( $Connect, "HELO $HTTP_HOST\r\n" );
$Out = fgets ( $Connect, 1024 ); // Receive server's answering cord.
