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.
