Well, try pbsdbd coming with qmail-ldap.
It uses a client / server architecture and afaik holds the data only
in memory. But every mail server acts as a client and can query every
other as server based upon the settings and list order in "pbsservers".

There is no need to alter the tcp.smtp.cdb. In the run file for
qmail-smtpd the client "pbscheck" is called before coming
to qmail-ldap.

We have used that for many years, also on our main mail farm which
is based on seven sun-fire server. Actually we do not use
pop-before-smtp anymore because we force our users to use
SMTP-Auth especially if they contact the mail server from foreign
ip addresses.
