The most likely guess is that you have a version of sendmail which does not read MX records. Instead it is perhaps using gethostbyname() in a version doing nameserver lookups. But if the code in sendmail is not DNS aware, it will not be able to distinguish between a temporary name lookup failure (due to your gateway problem) and a permanent failure due to a non-existent host. Most likely your only good solution is to get a better version of sendmail.
