Yes, I re-used wisdom from others, namely I learned that
sendmail does exactly that. A bit of local cacheing would
be benefittal inside the Zmailer resolver, but local named
can do it just as nicely..
ANY returns CNAME (alone) if that is what the thing
points to, else it returns something else and the
system knows it already has the canonic form, because
it didn't get CNAME..
(CNAME can't co-exist with SOA, for example, thus it
can never exist with NS either..)
If the DNS contains garbage, Zmailer may fall on false
information, but there is very little we can do to fix
such in the mailer...
