DNS zones for mail exchange, subdomain, smtp and pop3

[nabuk]

Hi all,
I've just installed isp config on a fedora core 6 mac mini server. all works without problem, but i've some issue with dns and mail services.
Under dns setting i've specificated the name of my name server and enabled default mx creation.
When i add a domain, like: host: www domain: test.com, i enable both create dns and dns-mx, but in the zone file, i can read only:

www MX 10 ns.test.com

but by selecting default mx creation i should have:

MX 10 ns.test.com
www MC 10 ns.2bite.net

mail A server_ip

Is this a bug or a configuration problem of my server ? After istalling isp config I've changed the ip, but i've changed all the configuration file found.

Also,
i need to have some domain with name@domain.com email and dome other subdomain with mail@subdom.domain.com email, how can i do ?



Thanks
