    From a DNS point of view,
    a properly configured mailserver should have:
    - a fixed, public IP
    - a A record
    - a MX record
    - a PTR record
    - propably SPF
    SPF: Project Overview

    If these basics are done, you can start configuring the mailserver itself.
    Most important: make sure it is no open-relay.

    Hi

    my issue is resolved, but i have a query for my knowledge sake.If i configure a DNS server, do i need to register my domain formally to some site, or will it work on my system's dnsdomain?

    While registering a domain, you can choose to have your own DNS.
    You need at least two.
    They have to be public reachable, ie have public and static IP addresses.
    As a consequence, you are then responsible for configutation, security and availability.

    ie:
    no DNS -> no mail
    no DNS -> no.. nothing

    hi

    I am still confused with the term 'registering the DNS'. Could you spread some more light on that..
