ok, you will need to create a recordset to return the allowed domains. After the recordset code, add the following code to loop through it and create a new variable that contains a pipe separated list of domains:


do {
$okDomains .= $row_recordsetName['domainName']."|";
} while (
$row_recordsetName mysql_fetch_assoc($recordsetName)); 
$okDomains substr_replace($okDomains,"",-1);

when you add the regular expression validation it will create a line similar to this:

$WAFV_Errors .= WAValidateRX(((isset($_POST["emailField"]))?$_POST["emailField"]:"") . "","/^[A-Z0-9._%-]+@(||$/i",true,1);

edit that to use the $okDomains variable instead of the static listing of domains:

$WAFV_Errors .= WAValidateRX(((isset($_POST["emailField"]))?$_POST["emailField"]:"") . "","/^[A-Z0-9._%-]+@(".$okDomains.")$/i",true,1);

make sure that the code order is correct, the validation may be placed before the recordset. The order needs to be:
-do to create the $okDomains variable
