http://www.vipul.net/ricochet/ - needs careful tuning though, and a degree of
intelligence (such as recognizing those mailservers which handle mail for
you [1] and not complaining there).

Distributed under the artistic license - so no hassles about commercialism.

[1] - Stuff like your ISP, your ISP's offsite backup MX if any, the
mailservers of any forwarding providers you use, etc ... fix ricochet NOT to
complain to these.  Oh, it'd be a slightly good idea to eyeball the complaint
once, before sending it out.

MAPS is not an autocomplain service.  However, you can reduce your spam load
by setting up DNSBLs to filter your mail.

User contributed = no.  However, extremely effective, if a bit radical = yes.
http://www.spews.org (and something to block mail from open relays - say orbz
or ordb).  Set up djb's rbldns (http://cr.yp.to/djbdns/rbldns.html) to
aggregate all the blocklists you use.  These are DNSBLs (like the MAPS
lists, but far more aggressive.  ORBZ / ORDB are so-called "son of orbs
lists" which will block all open relays they come across.  

Spews is extremely secretive about its identitiy .. nobody knows just who
they are, but as one of their users [on a large scale] I can say that the
information they dig up is pure gold :)  Several large ISPs stateside (SBC,
Prodigy, Ameritech etc) are already using spews to bounce mail.
