DNS MX Records Ubuntu 10.10
 
Hi All

I'm having a problem receiving external mail, i can send no problems and receive mail internally. So i used http://www.mxtoolbox.com to verify my DNS records and it returns that my MX record points to the IP 0.0.0.0. Which is not right.

Here are my DNS records copied straight out of the ispconfig control panel (proper names replaced):

A mail ***.***.***.189 0
A domain.tld. ***.***.***.189 0
A www ***.***.***.189 0
MX domain.tld. mail.domain.tld. 10
NS domain.tld. ns1.***.***. 0
NS domain.tld. ns2.***.***. 0

Please if anybody can see something wrong or if im missing a record? I did use the dns wizard to setup these records.

Any help much appreciated.

Is your ISPConfig server authoritative for your domain? You can check that by running
Code:

dig ns yourdomain.com
Also, you can check your DNS settings on www.intodns.com

Thanks Falko I ran a test on intoDNS and the mx record had this error:

Your MX records that were reported by your nameservers are:

10 mail.domain.tld No A Record (no glue either)

[These are all the MX records that I found. If there are some non common MX records at your nameservers you should see them below. ]

You must create an A record for mail.domain.tld.

Hi

So i added an A record like you said(below), but still nothing.

A mail.domain.tld. ***.***.***.189 0

Is there something wrong with it?

Is there a place i can check through ssh on the server where these records are stored?

If you use BIND, check out /etc/bind/named.conf and the files included in there.

You can also check your domain here: http://www.intodns.com/

Hi Falko

I can't see anything wrong, this thing is just driving me nuts.... Thanks for your help. www.intodns.com still giving the same story:

10 mail.domain.tld No A Record (no glue either)

Please check that your dns server is really the authoritive DNS server for this domain.

This is the response i get when running dig (i have no idea what this means):

Is the IP address displayed in the line ns1.otherdomain.tld the IP address of your dns server? If not, then your server is not authoritive for that domain.
