Force the use of WWW.domain

Hi,

I’d like to create domains which don’t start with www.
So I tried to configure my own DNS record template. But when I save the configuration virtualmin complains “A www A record for the domain must exist in the template”. How can I stop virtualmin forcing me of using www?
Why I don’t like www? I have subdomains which I don’t want them to have www in front (f.e. wiki.domain.tld).

Can anyone help me to get this template (below) working?

Regards,
Tobias

My Template looks like this:

[code:1]$ttl 38400
@ IN SOA server.domain.tld. ${EMAILTO}. (
2008111301
10800
3600
604800
38400 )
@ IN NS ns1.domain.tld.
${DOM}. IN A ${IP}[/code:1]

you dont create domains with www in front of it, just wiki.domain.com would be enough.
