Domain name as hostname

[Nick Bryant]

OR add the CNAME line in the same place. Just make sure it precedes the
$ORIGIN company.com. line. 

Either work.

Just add an A record for the parent domain.  It would look like:

    $ORIGIN company.com
    @	IN	SOA	ns hostmaster ( serial and ttl info )
	IN	NS	ns.company.com
	IN	A	111.222.333.444		;<--- note new record
	IN	MX	5 mailserver1
    www	IN	A	111.222.333.444

where '111.222.333.444' is the address of your www server.  This way
you don't have any CNAMEs or CNAME-generated problems.
