    Hi all,

    Need a help configuring BIND.
    I’ve setup a new server (let’s say, named: doc. 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 (

    What is intended is to have two subdomains one for students and other for other people (e.g. and with virtual users such as [email protected], [email protected], [email protected], etc., and to have the new server accepting mail for these subdomains.

    My questions is how to proper configure BIND so that email to [email protected],..., [email protected] will be delivered to the new server?

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

    $TTL 14400
    @      86400    IN      SOA (
                    2009101501      ; serial, todays date+todays
                    86400           ; refresh, seconds
                    7200            ; retry, seconds
                    3600000         ; expire, seconds
                    86400 )         ; minimum, seconds 86400 IN NS 86400 IN NS
    tels                    IN A
    ns2			    IN A IN A IN A IN MX 10
    mail        IN A
    www         IN CNAME
    ftp         IN CNAME
    So I think adding the following lines :
    Code: 86400 IN NS 86400 IN NS 	IN A 	IN A 	IN MX 10 	IN MX 10
    Is that a valid configuration?

    You just need

    Code: 	IN A 	IN A 	IN MX 10 	IN MX 10
    But if emails for should be deliered to a different server, the MX record for must point to that other server.

    Thanks for replying.
    Another question I’m facing now is about the reverse zones:

    Since I’m using IP’s on 196.28.228.XXX and 196.28.230.XXX, is that legal to create two reverse zones, and

    Yes, but usually your ISP that gave you the IPs create the reverse records for you. I'd ask them if they can do it for you.
