Quite.
When my ISP switched on greylisting my mail immediately went from a
spam:ham ratio of 80:20 to one of 20:80, which pretty much where it has
stayed ever since.
The soam:ham ratio is reported on a daily basis by my spamkiller filter
that I wrote and installed immediately downstream of my local copy of
SA. The filter quarantines spam for a week before deleting it. I don't
use my ISP's copy of SA because it didn't do a good job on some of the
maillists I get: my local SA does, but has a ruleset that is highly
customised for my mail stream.
