Hi All.
Nearly 60 hours since I activated greylisting.
The stats so far:
195 SMTP connections told to go away due to greylisting, of which 168
were told to come back in 5 minutes, the rest were MTA's retrying too soon.
83 unique IP addresses have been greylisted, 76 told to come back in 5mins.
1 Spammer was persistent enough to get around the greylisting but, as
previously posted, has been caught out by SA.
All in all, I'd say greylisting is a true winner for anyone wanting to
kill spam dead.

Thanks for the pointers to look in the folder.
Followed the rest of the instructions and my MX now greylists.
Goodbye spam (hopefully).
I'm sure many of us would appreciate it if you'd update the list in the
future on how well this works at preventing spam. (At least I know I
would.) I've seen mixed reviews about the efficacy of greylisting, and
I'd love to hear first-hand from someone using courier how effective it
really was.
