I've never heard of DNS spoofing before, can you explain? If this is just
people replicating my DNS servers, why is that a bad thing? And why would
anyone want to do that?
I hate announcing things like this on the list...

there is an A record for that one, so the sending MTA's have an ip on
which to try to dump your mail:
# dig dns.cdnet.com.mx a
; <<>> DiG 8.3 <<>> dns.cdnet.com.mx a

1. As I pointed out in the other msg replying to Phil's "you've got
no MX", you also don't have an A record for cdnet.com.mx, and that's
what's killing your delivery, after the sender MTA's cant' find your MX.
so, add an MX record, and A record, and you'll be ok.
2. Also restrict zone transfer on your DNS so you won't get spoofed.
When will you have my dedicated server ready? :)))
