Strictly speaking, your name server doesn't really care what all services are
running at any given IP address. DNS doesn't know anything about what services
are running on a host -- it only helps you find the host from its domain name.
What you need to do with the name server (i.e., QDNS) is to make sure that it
has proper MX records for each of your virtual domains, pointing to whatever
mail server will handle mail for that particular domain. IOW, for each domain,
you need a record like:
your.virtual.domain. MX 10 mail.your.main.domain.
where 'mail.your.main.domain.' is the host name that you've given to your mail
server (both in your DNS and in the mail server's config). There should be an
A record for mail.your.main.domain. You must also, of course, set up the mail
server so that it knows it's supposed to handle mail for your.virtual.domain.
