here is my prob :
I've a server named "serval"
domain : "d2i.fr"
ip addr : "184.108.40.206"
this server act as a web server and a mail server.
(OS: RedHat 6.0, sendmail 8.9.3 (pop3),
this server is also his own primary dns server, and another machine in another domain is the secondary dns server.
the dns server is declared to the NIC as www.d2i.fr
the server will act as a web server for numerous domains, and as a mail server for these same domains.
Each mail server should have, as name, mail.domain.com (i.e. mail.d2i.fr)
and web-site should be reached in my server by www.domain.com
for exemple : lvl-medical.fr will be hosted by serval.d2i.fr and mail server should be mail.lvl-medical.fr
What I need is a step by step method to configure dns files
