i'm not very versed in PHP. so i found this and ran it off my site(of course changed the email addresses) and didn't receive anything
<html>
<head>
<title>PHP Mail Array Loop</title>
</head>
<body>
<?php
$users= array (
"1rstaddress@wol.com"=>"John",
"2ndaddress@wol.com"=>"Paul",
"3rdaddress@wol.com"=>"George",
"4thaddress@wol.com"=>"Ringo");
foreach ($users as $key=>$val)
{
$subject="PHP Mail Test";
$message="Hello ".$val."<br>
This is just a simple form letter which can be sent to multiple locations.<br>
Best Regards<br>
Your Name (Webmaster)";
mail($key , $subject , $message , "From: youremailaddress@wol.com") ;
}
?>
</body>
