note 70401 added to function.getmxrr

This function has some strange side effects when dealing with aliases... My function: if (getmxrr($fqdn, $mx_records, $mx_weight)) { // copy mx records and weight into array $mxs // ignore multiple mx's at the same weight for ($i = 0; $i < count($mx_records); $i++) { $mxs[$mx_weight[$i]] = $mx_records[$i]; } // sort array mxs to get servers with highest priority ksort ($mxs, SORT_NUMERIC); reset ($mxs); } else { // No MX so use A $mxs[0]= $fqdn; } fails because a $fqdn containing an alias returns a true yet on return both $mx_records and $mx_weight contain nothing! The solution until this gets fixed is to replace if (getmxrr($fqdn, $mx_records, $mx_weight)) with // Handle aliases etc. if ($result = getmxrr($fqdn, $mx_records, $mx_weight)) { if(!isset($mx_records) || (count($mx_records) == 0)) $result = false; } // Process MXs if ($result) { Hope this helps others....
