The answer depends a lot on how bad FPs are for you.
I trust zero RBLs enough to use for outright blacklisting.
At the MTA layer, I use 3 RBLs to trigger greylisting. (yes, unlike most
greylist configs, I don't greylist by default, but use milter-greylist's access
lists to selectively greylist email that's highly likely to be spam). This is

I do all my RBL blacklisting at MTA level, I use the main ones such as
Spamcop and Spamhaus plus a few others, if you're on a blacklist I
don't accept email from you period....no ifs no buts, I process a few
million emails a month for my clients and get no complaints!<br>
<br>
It reduces the load dramatically on the MailScanners because its a
black and white decision made at MTA level.<br>
<br>
Works flawlessly for me and my clients...<br>
