Hey,

The only things I could say are as follows:

Do you really need a TTL of a week? 3 days seems more sensible. Also,
you might want to use the W, D, H and M notation in zone files rather
than seconds, to make it much more readable.

Did you mean "ns.exoco.net" here? If you're intending to use
ns.exoco.net as an authoratitive name server for exoco.net, you'll need
a glue record to hold it all together.

A hidden primary configuration is something you may want to consider
looking into. Basically having a primary server that just holds the zone
files, but is never queried directly for records, it lets other servers
which have already pulled the zone data from it do that.

If you're intending to use this box as an outgoing smtp relay/origin,
it's a very good idea to have reverse DNS set too.

It won't break anything per-se, but it's bad practice as Andy has
already said.

Cheers,

Paul.
