What someone said about qmail accepting all mail
and then relying on brute force to verify recipients
is only true of an unconfigured qmail, an unfair
comparison. If one configures the "locals" file to the
same standard of any other recipient database
constituting a comprehensive directory of all authorized
users(ldap, mysql, berkeleydb, another flatfile like
"locals"), then it is possible to bounce before accepting.

qpsmtpd is an all-perl mta replacing most but not
all qmail services. There is a high_perf branch,
developed by Matt Sergeant, who receives two
millions spams a day with it.

http://perlq.org/ qpsmtpd all-perl frontend for qmail

qpsmtpd relies on qmail to relay to non-local
addresses. You have your choice of also using
ldap, mysql, flatfile, or if you have properly
configured qmail's locals file to verify individual
recipients then you could let qmail handle all
mail after using various protocol checks and
clamav and other virus checkers.

I am presently using qpsmtpd, ldap, lmtp to
dspam, then cyrus2.2. You would have to
do quite a bit of work in perl and bash scripting
to build a system like that, as far as integrating
ldap with dspam and mysql and cyrus. I have
about fifteen scripts for merging of user lists
and mailboxes, and three custom plugins for
qpsmtpd, a sendmail replacent script, and
cyrus sieve script features that help the
integration of mta and dspam and cyrus.
