Not really, no.

Howwever I have grown quite strongly oppoesed to add special
(disabled by default) greylisting code to the default configuration.
Judging from reading exim-users there seem to be two widely different
approaches to greylisting:

#1 run it very early (after rcpt verification) since it is cheap on the
   recipient side
#2 run it late, only for suspicious senders (i.e. after DATA, for high
   spam-scores)

Also at least for #2 people often do away with the daemon and use
exim's sqlite lookup http://wiki.exim.org/SimpleGreylisting

There are multiple daemons available, most requiring different setups.
(Me personally I am using postgrey.)
