You can either add them via the GUI in the Control Panel under email,
the blocking field there, or edit /etc/mail/access by adding them below
the line:
# Put custom additions below (Do not change/remove this line).

Then add stuff like:

grzzr.com	550 screw off spammer
da.uu.net	550 Mail rejected DUL
email-4-prizes.com	550 Mail rejected Spammer
emailhello.com	550 Mail rejected Spammer
emailoffersdirect.com	550 Mail rejected Spammer
emailofferz.com	550 Mail rejected Spammer
emailpromoter.com	550 Mail rejected Spammer
emailrewardz.com	550 Mail rejected Spammer
emailsvc.net	550 Mail rejected Spammer
emailshoppingnetwork.com	550 Mail rejected Spammer
emailyoulike.com	550 Mail rejected Spammer
emarketing365.com	550 Mail rejected Spammer

There are tons more. Once you save the changes to /etc/mail/access you
run:

makemap hash access.db < access

I generally find enough spam being sent to my old Internic contact
addresses to add a lot of domains and plenty of IP blocks. They still
get through, thanks to the tons of servers out there that pop up running
open SMTP relays.
When I get spam, I'll check the IP against one of the relay checking
sites and add it to the list.
