I've had several setups for SPAM/Virus handling in qmail servers,
and the best solution so far was a combination of simscan + dspam +
clamav. All the other qmail-queue replacements i've tried, including
qpsmtpd, where just too expensive regarding system resources. Most
solutions involving perl will simply not do, at least for me, on account
of perl overhead.
Right now i have several production environments, one of which is
rather large, and i've been rather happy with the implementation
outcome. That setup includes qmail-ldap with some patches for
greylisting and greeting delay, simscan with a patch to handle dspam
internal quarantine engine, dspam with a patch to allow user
checking/address alias mapping, clamav, maildrop for server side
filtering and finally dovecot with Johannes dspam plugin.
Besides the regular locations for all that software, you might
consider taking a look at the set of patches i mentioned. The link is
