    Confused :(

    Do your customer want:

www.xyz.com pointing to the same IP as www.abcd.com

    without having to manage xyz.com?

------

With bind:

    zonefile xyz.com

    $ORIGIN     xyz.com.
    <yadiyada TTL SOA>

    $INCLUDE    domains/abcd.com.all

     zonefile abcd.com

    $ORIGIN     abcd.com.
    <yadiyada TTL SOA>

    $INCLUDE    domains/abcd.com.all

    Just make sure nothing is the .all has the .abcd.com. (dots are
important).

Without bind:

    Good luck.

short answer: can't be done

You cannot have a cname and 'other' information for same entry.  As a
zone requires an SOA record, you cannot have a CNAME for the entire
domain (theoretically a registrar could do it in .com, but afaik
nobody does his).

Depending on customer's requirements, can put in a  wildcard 
*.abcd.com in cname xyz.com

Or can load the same zone file for both abcd.com and xyz.com, so in
both, mail<domain> goes to the same place

Hi All,
One of our customer having the following requirement.

There is a domain abcd.com ( zone file created , A records are
pointed ).
He has another domain xyz.com. He want us to create a separate zone file
for " xyz.com " & abcd.com should be the CNAME of it. ( No "A" records
mentioned )

I'm bit confuse about adding this in zone file. Can any one help ? :(
