[SDBUG] OpenBSD's "spamd" usable on FreeBSD?

[Geoffrey Sanders]

No...

He's actually referring to spamd by Bob Beck of the
OpenBSD development team. Many like it better because
it acts as a tarpit (by interacting with pf) using
white/grey/blacklists (rather than just filtering
based on hash signatures), in addition to the fact
that very little legitimate mail is ever flagged. The
advantage is that it requires very little overhead to
run based on spamd's design. It doesn't get
everything, but then, nothing does. However, it
doesn't contain the overhead of most other
applications designed for this either.

It has also been ported to FreeBSD.
