[H-GEN] The declining effectiveness of SpamAssassin

I've been having a look at my spam logs, as I've had the feeling
that I'm personally dealing with a lot more spam recently.

Twelve months ago, SpamAssassin identified 80% of the spam that
made it past my other defences; as a result, I only saw about 4
spam messages a day.  Now, SA is only catching 61% of the spam
and the ever-increasing volume of spam means that I'm seeing 48
spam messages a day in my inbox.

I could live with 4 a day; but 48 is just too much.  I'm curious
to hear from people who have found better ways of keeping on top
of this problem.

One detail: although SA has been upgraded several times since I
began using it, I'm still using version 2.44.  I'm planning to
test version 2.63 in the next few days to see whether it has
evolved enough to make it more useful.

The problem now, however, is that my anti-spam measures have to
be 97% effective to get my daily dose back down to 4 or 5 spams,
and I'd be astonished if SA can approach that.

Cheers, Greg
