DNS - MX record not getting from dig

jose_tk · 10-22-2009, 07:51 AM

Dear all,

After I create a new zone entry and RR for a mydomain.com,
the Nameserver not offering the MX record.

The following is my RR file in the master

$TTL 1D
@ SOA ns1.mynameser.net. dnsmaster.mydomain.com. ( 2009102215
3H
1H
1H
1H )
IN NS ns1.mynameser.net.
IN NS ns2.mynameser.net.
IN NS ns25.domaincontrol.com.
IN NS ns26.domaincontrol.com.
@ IN 7200 A 80.227.124.13
mail.mydomain.com IN 7200 A 80.227.124.3
IN 7200 MX 10 mail.mydomain.com.
www IN 7200 CNAME mydomain.com.

While 'dig' ing for MX, I am getting the following information.

root#>dig @ns1.mynameser.net mydomain.com MX

; <<>> DiG 9.3.3rc2 <<>> @ns1.mynameser.net mydomain.com MX

Is something wrong in the RR file?
Appreciate your time.

You have a couple of errors in the zone file:
You have mixed ttl with class IN. You missed the trailing dot at mail.mydomain.com. Also move the MX record right after the NS records and make sure you leave at least a space before IN.
If you need the ttl then use this zone file:

Code:

$TTL 1D
@ SOA ns1.mynameser.net. dnsmaster.mydomain.com. ( 
2009102216
3H
1H
1H
1H )
 IN NS ns1.mynameser.net.
 IN NS ns2.mynameser.net.
 IN NS ns25.domaincontrol.com.
 IN NS ns26.domaincontrol.com.
 7200 IN  MX 10 mail.mydomain.com.
@ 7200 IN  A 80.227.124.13
mail.mydomain.com. 7200 IN  A 80.227.124.3
www 7200 IN  CNAME mydomain.com.

I agree with bathony response, may I offer the following zone file based on your material as an alternative.

Code:

$TTL 1D
@		IN  	SOA  	ns1.mynameser.net. dnsmaster.mydomain.com. ( 
					2009102217	; Serial
					3H		; Refresh
					1H		; Retry
					1H		; Expire
					1H 		: Minimum TTL
					)

; Name Servers				
		IN 	NS 	ns1.mynameser.net.
		IN 	NS 	ns2.mynameser.net.
		IN 	NS 	ns25.domaincontrol.com.
		IN 	NS 	ns26.domaincontrol.com.

; MX Record
		IN 	MX 10 	mail.mydomain.com.	

; Names
		IN 	A 	80.227.124.13		; NULL record
mail		IN 	A 	80.227.124.3
www 		IN 	CNAME 	mydomain.com.

In addition, here are a couple of links on DNS to assist you.
