According to Yarema:

Well, that's not true for 8.8.8+Assman's rules and 8.9 (which by default
forbid relaying); use of the RBL is only

FEATURE(rbl)dnl                 # 8.9.0

and

define(`_MAPS_RBL_', 1)dnl      # 8.8.8 + check.tar

away.

8.9.0 has one very cool feature for hosts that are listed as MX for many
domains: if you use the following, you'll authorize relay from all every
domain you're MX for:

FEATURE(relay_based_on_MX)

One site I'm administrator for has a lot of UUCP connected machines and the 
above feature makes very easy to accept mail for all the various domains
our users have without having to list every one of them...
