Have just installed ISPConfig 3 and managed to to make it work to ~95%. When it comes to DNS configuration, I'm just a newbie. Made some self-studies on the internet about DNS and got some sort of grip on the matter. But thats all.
My ISPConfig server is hosted on VPS from a ISP. They also provides their DNS server for my domain, where I can configure records through a panel.
I have only changed the IP-address in the default ISP settings, where "123.456.789.12" is the IP for the server which runs ISPConfig. They look like this:
(IP adresses are fictive)
Subdomain Type TTL Data
@ A 3600 123.456.789.12
www A 3600 123.456.789.12
In the DNS records in the ISPConfig 3 panel, I have the following entries:
(Domains and IP adresses are fictive)
A domain.com. 123.456.789.12 0 3600
A mail 123.456.789.12 0 3600
A www 123.456.789.12 0 3600
MX domain.com. mail.domain.com. 10 3600
NS domain.com. ns1.domain.com. 0 3600
NS domain.com. ns2.domain.com. 0 3600
I can reach the website on www.domain.com
But when I make a ping to the mail.domain.com
from an "outside" computer, I receive the "Unknow host" message. So something is not properly configured for sure.
Any suggestions, please...?
