named config: how do I remove an MX record?

[shakin]

I've sort of been thrown into this one. I've never admined a DNS server before.

Anyway, we're running named and I think I found the config in /var/named/

When I 'vi domain.com.db' I see entries like the following:

                   IN      MX      20      mail2
mail2           IN      A       xxx.xxx.xx.xxx

So I commented both lines out by putting a semi-colon in front of them. I then restarted named by running '/etc/init.d/named restart', but even on that box, which runs 127.0.0.1 as its primary DNS server, I can still resolve the domain mail2.domain.com.

What am I missing? What's required to do this? I'd be equally happy removing the record or simply changing the mail2 IP to a different server.

Thanks.

Did you change the serial number after you made the changes and before restarting named? This must be done to let named know that you did some changes.
