Lame DNS server

Your named.conf lists the zone as destinosxures.com while the zonefile itself refers only to destinoxures.com (note missing central "s"). If that reflects what's really on your server, then it's definitely a problem.

And may I in passing thank you for not obscuring the domain name in the question; if you had, we'd likely never have found the answer. Others who are posting questions, particularly DNS questions, please take note.
