I agree with Michael that spamdyke is great. Highly recommended.
I'd like to clarify the tcpserver -h option though. This option does do
an rDNS lookup which is duplicative with spamdyke, but I think it's best
to do both, as they're used for different purposes. Spamdyke uses rDNS
for blocking. Tcpserver's -h option simply sets the TCPREMOTEHOST
variable, which does no blocking of any kind, but does provide more
complete logging messages. The overhead of the duplicate rDNS lookup is
negligible (immeasurable I expect), since the lookup is cached. That's
why I think it's best to have both.
Sam C (spamdyke's author) discusses this (and other things) here:

Are you using SpamDyke? If so, and you are checking for RDNS there, that
would seem duplicative to me. I block any mail server that does not have
RDNS using SpamDyke. Better to stop it there than waste time scanning it
with SpamAssassin...

Found it myself:
In /var/qmail/supervise/smtp/run, I had forgotten to enable rDNS (default
seems to be off), by changing the -H flag to -h.
Thanks,

Hi all,
There is something weird I noticed in my logs: every email I receive
gets marked as RDNS_NONE by spamassassin. This was not the case with my
previous setup. lookup and reverse lookup work, so I am at a loss as to
why this is? Perhaps some perl module I have not installed, etc?
