We have an own Windows 2000 server running with a couple of IP-adresses on the NIC and ADSL connection with the outside world. The server has Active Directory deployed (local domain). We have a FQDN (ourdomain.com) pointing to our server. In order to host this domain, we have our own DNS server (MS implementation) running. I think it's properly configured because the outside world has no problems reaching our www, ftp and news server.
The only thing is our mail server. Server diagnostics in Merak admin console gives the following error:
Primary Domain Test Error.
Either the Internet connection is down or the Primary Domain does not have a proper MX record.
I have Merak mail server working properly *within* the office, only the outside world cannot reach it (I can send mail from within to outside using own mail server on 'mail.ourdomain.com'). The mail.ourdomain.com however is not recognized as a mail server.
This is how I have implemented it in DNS:
Within the ourdomain.com zone it has (amongst other) the following records:
<i>name</i> --- <i>type</i> - <i>data</i>
mail A 10.0.1.1 (=internal NIC)
mail MX  mail.ourdomain.com
If anyone has any suggestions what is possibly wrong I would be very grateful for your help.
