I have pretty much the same setup except that I disabled SA in
amavisd-new (because I don't like the way amavisd-new handles SA
reports), using it only as an antivirus "frontend" for postfix. Instead
I use spampd to do the real spam detection. spampd is a perl daemon,
which (like amavisd-new) acts as a sort of SMTP proxy, but unlike
amavisd-new (which uses spamc/spamd unless I'm mistaken), it uses
SpamAssassin's perl modules directly. SpampD is quite efficient as it
only loads all spamassassin rules only once (like spamd) and tries to
avoid spawning of new childs (as far as this is reasonable).
Have a look at http://www.worlddesign.com/index.cfm/rd/mta/spampd.htm
for spampd (original author) or just use my Debian packages (in
Debian/Stable) if you use Debian.
