Solved DNS MX record setup

[cesjr]

I have register test.com.tw with 200.200.200.1, and below is NS and MX record:

Name Server: ns2.test.com.tw
Name Server: gate2.test.com.tw
MX     Server: mail2.test.com.tw
MX's A record is 200.200.200.2

If I register a domain abc.com and also set NS record just like above.
may I also set mail2.test.com.tw as abc.com MX server?
If it does ,how to do ?
If not ,why?

Yes, you can do that. A bind zone record for abc.com would look like

@    MX    0   mail2.test.com.tw.

(Note the period at the end of the name)

http://www.zytrax.com/books/dns/ch8/soa.html gives some information on the meaning of all that.

To expand on that, all records for a domain must be served by the authoritative server for the domain and you can't mix records between different zones. This means that you have to have one zone for test.com.tw and another separate one for abc.com. Both zones can be served by the same instance of BIND (or NSD or PowerDNS etc if desired) though.

Thanks all suggestion , I using two separate zone :

@  MX  0  mail2.test.com.tw.
@  MX  0  mail2.abc.com.

Both MX indicate to same ip address , that means both zone are in same server
