I was assuming that all the qmail doc I've worked with have noted that
a working DNS server is required for use with private addressing on
a LAN. You need to setup tinydns (not dnscache), bind, or a similar
nameserver to serve the proper DNS lookups for your LAN. A further
note, since you are using this domain on both the LAN and the DMZ,
both segments will need to use this nameserver as Ray (IIRC) noted
earlier. This is to prevent resolving the domain to your external address
which should be blocked with ip spoofing rules.
