The Qmail in the DMZ must communicate with the internal LAN, mustn't it?
How else do your internal users get their email?
The following suggestions are based on the information you provided;
without a statement of all your information requirements it's hard to
provide an accurate answer. ;)
Your LDAP server would probably be best in the internal LAN, mainly
because I expect this to be where the primary clients will sit. What
protocol(s) will Qmail require to communicate with the LDAP server?
If your firewall is secure, and your servers are patched and properly
configured then you should be fine having the Qmail communicating with the
LDAP server; I'm assuming it already communicates with internal email
servers or clients.
If this all sounds mad then provide some more info and I'll have another
