Just add @ before checkdnsrr:

list($userName, $mailDomain) = split("@", $buyer_email);
if (@checkdnsrr($mailDomain, "MX")) {

But you shouldn't use @ as it will make a PITA to find errors in your code
when maintaining it. You should not display Warnings on production too, at
least not for users but instead log those.
