I don't know when that was. Razor2 appears to be quite fast, unless you
set it up to automatically submit all caught spam to razor.

My mileage has been about 60%-70% of spam was listed in Razor2, the rest
was caught by SpamAssassin.

As I said, this could be a case of wrong setup, or older Razor. I have
crontab call up fetchmail every 10 minutes from 2 pop accounts. The mails
are delivered to postfix which calls procmail and procmail fires up
SpamAssassin. Even when I get 50 emails on several mailing lists (and my
mailing list rules are below the SpamAssassin rule) it still takes only a
minute or two.

I've had far fewer misses. About 1 in 30, constantly. And about #3 - yep.
Same happened to me.

Hey, experiment... Set things up so that 4-5 spam level goes into a
separate folder, and see how many false positives you get. That will help
you decide.
