Also consider the invalument block lists, see http://dnsbl.invaluement.com/
A very, very good list that is usable for blocking. Not free, but
very affordable.
I don't like how involvement does their pricing structure, actually.
Firstly, I don't feel comfortable telling a 3rd party how many 'users'
I have. Secondly, I don't feel like determining what they consider a
'user'. Third, because of my HELO/EHLO restrictions and rejection of
unknown users I make FAR fewer RBL calls than most mailservers (I
reject about 87% of all connections, and 98% of those rejections are
in HELO/EHLO or unknown, Only 0.66% over the last week rejected by
zen's RBL), so if I used invalument, it would probably only be for a
handful of callouts per day but I would be paying the same amount as
someone who was using it to do many tens of thousands of callouts per
day.
Sure, $20 a month is not a lot of money, but looking at my mail I
figure that would be costing me about 1/2 a cent per check, if not
more (I average out only about 1000 checks of zen per week), assuming
I made exactly as many checks to involvement as zen means slightly
over 1/2 cent per check.

You choices are half chance; so are everybody else's.
