Yes, if you have your qmail on your DMZ, just point MX to the public address
and you can
'route' your mail with smtproutes:

rccn.net:x.x.x.x

  or 

.rccn.net:x.x.x.x for subdomains.

Cheers,
Fred

Yes, that's just what you want.

I can't think of any other. Just keep in mind you still have to add the
domains to the "rcpthosts" file (but not in "locals"). And the inner
machine will also need the same "rcpthosts", plus "locals" or
"virtualdomains", depending on how you set it up.
On the optimization side, you have 2 choices:
- Either route all mail to the inner host, and let it handle everything
  (not a _bad_ idea, but...)
- Specify a route each and every domain you want forwarded in "smtproutes". 
It possibly takes some load off the inner host, and is easier to change if
you ever want to split the processing of different domains' mail through 
different mailservers.

yes, it is...
in fact, many companies hide their (e.g. m$ exchange) server that way.

Yes, this is one way.  Configure the DNS so your MX record points to the public
interface of a qmail box in the DMZ.  Then in that machine's
/var/qmail/control/smtproutes, place an entry for your internal domain name
pointing to the internal-only mail server.

Local delivery in 2 SMTP hops

[jpsp]

Hello there,

I would like our mail to be firstly delivered 
to my organisation's DMZ (through a regular
primary MX record), and then to make it 
route to our internal network (private
IP addresses).

I think a "smtproute" that overrides the
DNS configuration might do it, but I'm
not sure.

Is this the proper way of doing it?

Thanks,
jp
