qmail is hardly likely to issue (and get confused by the results of) an
(IN,ANY,'.') query, as it isn't syntactically possible to use the root
as a mail domain.

For other domains (even TLDs) - sure. qmail users need to get their
systems fixed, see e.g. http://lifewithqmail.org/lwq.html#dns-patches
