Virtual domains & BIND configutation

[thavaht]

Hi all,

Need a help configuring BIND.
I’ve setup a new server (let’s say, named: doc. my_site.ac.mz) following a “virtual users and domain howto” and it works fine.

In my organization, a educational organization, there is a mail server running and configured to accept mails for the domain (my_site.ac.mz).

What is intended is to have two subdomains one for students and other for other people (e.g. doc.my_site.ac.mz and stu.my_site.ac.mz) with virtual users such as user1@doc.my_site.ac.mz, user2@doc.my_site.ac.mz, user1@stu.my_site.ac.mz, etc., and to have the new server accepting mail for these subdomains.

My questions is how to proper configure BIND so that email to user2@doc.my_site.ac.mz,..., user1@stu.my_site.ac.mz will be delivered to the new server?

So far the zone I’ve set up looks like follows:

$TTL 14400
@      86400    IN      SOA     tels.my_site.ac.mz. hostmaster.my_site.ac.mz. (
                2009101501      ; serial, todays date+todays
                86400           ; refresh, seconds
                7200            ; retry, seconds
                3600000         ; expire, seconds
                86400 )         ; minimum, seconds
my_site.ac.mz. 86400 IN NS tels.my_site.ac.mz.
my_site.ac.mz. 86400 IN NS ns2.my_site.ac.mz.
tels                    IN A 196.28.228.224
ns2			    IN A 196.28.228.223
my_site.ac.mz. IN A 196.28.228.223
localhost.my_site.ac.mz. IN A 127.0.0.1
my_site.ac.mz. IN MX 10 mail.my_site.ac.mz.
mail        IN A 196.28.228.223
www         IN CNAME mail.my_site.ac.mz.
ftp         IN CNAME mail.my_site.ac.mz.

So I think adding the following lines :

doc.my_site.ac.mz. 86400 IN NS tels.my_site.ac.mz.
stu.my_site.ac.mz. 86400 IN NS tels.my_site.ac.mz.

doc.my_site.ac.mz. 	IN A 196.28.230.99
stu.my_site.ac.mz. 	IN A 196.28.230.99

doc.my_site.ac.mz. 	IN MX 10 doc.my_site.ac.mz.
stu.my_site.ac.mz. 	IN MX 10 doc.my_site.ac.mz.

Is that a valid configuration?
TIA,
thavaht
