Spam: Google + Spamassassin

My current spam solution combines using Google as a filter and then sending to Spamassassin. I have Spamassassin set to a threshold of four (4), and I wondered when I implemented this solution recently how much would get through Google but get caught by Spamassassin.

Well, over the last week I’ve caught thirty (30) spam messages with SA — and that requires that they make it through Google to even be seen by that filter. So that’s 30 out of approximately 1,400. Google’s doing a great job, in other words, but I like having the second filter anyway.
