evolution and spamd

[Kenny Hitt <kenny@hittsjunk.net>]

Hi.  Could someone please point me to docs on how to make evolution use
the system wide spamd instead of spawning it's own copies.  I'm running
evolution version 2.0.3-1.2, spamassassin version 3.0.2-1, and Gnome 2.8  on Debian unstable.

Thanks in advance.
