Mail Problem: DNS Error: Domain name not found

Hi guys,

we have found a strange behavior of the domain: mydomain.com.
This domain receives all the email from the most important mail services but none from gmail.com

This email was sent by the server where it has been registered.

Code:

                   The mail system

<[email protected]>: Host or domain name not found. Name service error
    for name=mydomain.com type=A: Host not found

If I send an email from gmail.com I get this error:

Code:

*DNS Error: Domain name not found

The strange thing is that the mail server receive correctly the email from other mail services like yahoo.com and other.

Any idea?

 

Did you check your domain on www.intodns.com ?

 

Hi Falko,

thanks for your reply. Seems all ok.

Look here: http://tinyurl.com/chyonqf

Really strange.

 

Does the A record of your domain exist and point to the correct IP? Do the nameservers that you use in /etc/resolv.conf resolve the domain correctly?

 

Hi falko,

yes the A record point directly to the right web server. In the webserver there is a mail domain with the name of the domain registered.

Yes, the nameservers resolve correctly the domain.

Thanks

 

intodns shows this warning:

I'm not sure, but maybe you should lower the expire - maybe this causes the problem.

 

How have I change the SOA expire time?

thanks

 

Try 3600 instead.
