BIND Not Responding Properly to Dig Requests

Hello,

I'm having a problem with an ISPConfig installation, specifically with BIND.

I can't post the domain because it is not my box, but here is the problem using example.com. ISPConfig is installed on host.server.net

pri.example.com file:

Code:

$TTL        86400
@       IN      SOA     host.server.net. admin.example.com. (
                        2008020606       ; serial, todays date + todays serial #
                        28800              ; refresh, seconds
                        7200              ; retry, seconds
                        604800              ; expire, seconds
                        86400 )            ; minimum, seconds
;
                NS      host.server.net.              ; Inet Address of name server 1
                NS      host.server.net.              ; Inet Address of name server 2
;

mail.example.com  MX      10 216.254.178.179.

example.com.      A        67.69.17.174
example.com.       TXT  "v=spf1 a mx ptr ~all"

;;;; MAKE MANUAL ENTRIES BELOW THIS LINE! ;;;;

BIND is running without errors. However, when I attempt to dig the MX record from host.server.net, it doesn't return the MX record:

Code:

 dig @host.server.net  mx example.com

; <<>> DiG 9.4.1-P1 <<>> @host.server.net mx example.com
; (1 server found)
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39353
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0

;; QUESTION SECTION:
;example.com.             IN      MX

;; AUTHORITY SECTION:
example.com.      86400   IN      SOA     host.server.net. admin.example.com. 2008020606 28800 7200 604800 86400

;; Query time: 291 msec
;; SERVER: host.server.net#53(host.server.net)
;; WHEN: Wed Feb  6 17:15:33 2008
;; MSG SIZE  rcvd: 96

It does give out A records without a problem, it's just the MX record that I can't get:

Code:

dig @host.server.net  example.com

; <<>> DiG 9.4.1-P1 <<>> @host.server.net example.com
; (1 server found)
;; global options:  printcmd
;; Got answer:

;; AUTHORITY SECTION:
example.com.      86400   IN      NS      host.server.net.

;; Query time: 212 msec
;; SERVER: host.server.net#53(host.server.net)
;; WHEN: Wed Feb  6 17:18:39 2008
;; MSG SIZE  rcvd: 84

I have restarted BIND and manually checked the files, but I just can't see it.

Anyone know why BIND isn't giving out MX records when requested?

 

Your setup is wrong. You need this

Code:

example.com MX 10 mail.example.com.
mail.example.com A xxx.xxx.xxx.xxx

Right now what you have is an mx record for the mail.example.com domain not example.com

NOTE: on a side note RFC requirements do not allow you to have an IP address as a MX it should be a name

 

Awesome, thanks for the help. Just leaving the host name blank cleaned it all up.
