That is easy, though qpsmtpd on Debian was pretty easy as well. The
main catch was to move qmail to listen only on localhost, since the
external interface now has qpsmtpd instead.

So far, so good. No spam in the spambox this morning, at all. Most
were caught by the Spamhaus DNS blocklist I already use, but the
greylist whacked the remainder. 

Some of the other plugins look interesting too, but weren't involved
in the first few hours. They basically look for weird behaviour which
spammers engage in, such as starting to chatter before the SMTP
greeting. I'm leaving the log level high for a bit, as I'm curious
about how often these show up.
