if you can't wait for a vendor fix, check out smtpd:
it's freely avail. a drop-in replacement for smap/smapd. runs in a chroot
environment, forks off the MTA of your choice for delivery (sound familiar?)
& has the most sophisticated anti-spam features i have found.
i replaced smap/smapd with smtpd about 3 months ago & have been very
pleased with the results. no relaying & much, much less spam.
useful for ISP's who have to handle a large number of domains as it has
the ability to match on the nameserver a domain is using. same feature
is also useful for dropping mail from known spamhauses.
smtpd can also defer mail from domainnames which do not resolve quite easily.
check out the docs for the full list of features.
hope this helps,
