Spamassassin is not even close to being dead.  They may not have
released a new software version in over a year, but the spam definitions
are being constantly updated (last update 7/7/2012).

There are also a few third-party SA rulesets that can help out quite a
bit.  I use these:

Sought  (http://wiki.apache.org/spamassassin/SoughtRules)
khop (http://khopesh.com/wiki/Anti-spam)

The only blacklist I trust for blocking is Spamhaus' Zen list.
