Setting up BIND9

[AutootuA]

I'm trying to setup bind9 on Ubuntu Server 6.06. I want to make sure that I have it configured correctly for Zimbra. The machine name is "mail" on my domain "nunyad.biz". I want to send and receive emails like user@nunyad.biz. Should nunyad.biz and mail.nunyad.biz both have a MX record???

/etc/bind/named.conf.local

//
// Do any local configuration here

        zone "nunyad.biz" {
                type master;
                file "db.nunyad.biz";
                allow-update { none; };
        };

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

/var/cache/bind/db.nunyad.biz

;
; BIND data file for local loopback interface
;
$TTL    604800
@       IN      SOA     mail.nunyad.biz. admin.mail.nunyad.biz(

                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      mail.nunyad.biz.
        IN      MX      10 mail.nunyad.biz.
        IN      A       192.168.254.160
mail    IN      A       192.168.254.160
www     IN      A       192.168.254.160

When ever I do a "nslookup" on mail.nunyad.biz and nunyad.biz I get:

Server:         192.168.254.160
Address:        192.168.254.160#53

Name:   mail.nunyad.biz
Address: 192.168.254.160


Server:         192.168.254.160
Address:        192.168.254.160#53

Name:   nunyad.biz
Address: 192.168.254.160

But when i run "host -t mx domain":

host -t mx nunyad.biz
nunyad.biz mail is handled by 10 mail.nunyad.biz.

host -t mx mail.nunyad.biz
mail.nunyad.biz has no MX record

You created incorrect BIND9 zone

$TTL 2D

There's nothing wrong with the zone file (apart from it really should have 2 nameservers ideally).

host -t mx nunyad.biz
nunyad.biz mail is handled by 10 mail.nunyad.biz.

host -t mx mail.nunyad.biz
mail.nunyad.biz has no MX record

This is correct. The hostname shouldn't have an MX record, just the domainname.

This Wiki Article goes through the entire install of Zimbra on Ubuntu Server, including the configuration of bind. I wrote it because I found it impossible to get an after-the-fact installation to behave properly with bind or bind9, but I have replicated this installation methodology several times without a hitch.

Hope it helps,
