Hi,
I have a quick bind question. I want to set the MX records on a domain to
something normal but I want to set the MX for all subdomains to something
else.
example.com mail.example.com
xxx.example.com blackhole.example.com
Thanks in advance

It didn't work - but this might be related. I have this in there as wellso
that all A record subdirs resolve to the same IP.
mail IN CNAME mail.ctyme.com.
mailman IN CNAME mailman.ctyme.com.
mailman.mailman IN CNAME mailman.ctyme.com.
ssh IN A 65.49.42.101
ftp IN A 65.49.42.101
www IN A 65.49.42.100
* IN CNAME @
OK, I guess I didn't understand -exactly- what you're trying to do.
If you say "all subdomains" do you mean multiple levels or a single
level?
IE:
dig example.com mx
to return: preference = 10, mail exchanger = mail.example.com
and
dig anything.example.com mx
to return: preference = 10, mail exchanger = blackhole.example.com
but what do you expect
dig this.that.example.com mx
to return? What about 5 levels deep? How far down do you plan on
going?
Also do you plan on having -any- other records other than MX in that
dummyed domain? (Based upon your data above it looks like you do,
that complicates the situation).
Get rid of that wild-card CNAME record, replace it with an explicit
MX record pointing to your blackhole server.
