qmail does not... it checks for any valid MX record for a domain. You have 
to publish your MX records for your domain publicly using tinydns, part of 
the djbdns package, or some other DNS service. You will never receive mail, 
or get hits on Apache if you do not have published you DNS records somehow. 
There are some free services that will allow you to sign on and they will 
update your IP addresses on their DNS if they are dynamic.
