Nope, 2GB of RAM in this thing, it's not even all used.

I have to finish them faster than they come in, though... SA takes about 1.5
seconds when it's slow (big mail), so the concurrency has to be big enough to
allow for this given a few per second coming in.

I'm just throwing | spamc in the big .qmail-default.  I don't assume there's a
more efficient way to do that.  I'm not interested in filtering outgoing mail.

Are there any good pre-learned Bayesian filters for SA?
