I don't know about all that, but I have implemented
greylisting on Fedora Core 4 (exim self compiled) and
Debian with exim4-daemon heavy, which both include
what used to be known as the exiscan patch and is now
merged into the main codebase for Exim, you just have
to find the right configure option if you're compiling
yourself. I don't know if you need this for calling
out to greylisting functionality, but I did find an
exim heavy package for Fedora Core from one of the 3rd
party repos.

I have the process detailed on my blog at:

http://blog.adamsweet.org/?p=172

but the \ characters keep getting stripped out and I
don't know how to solve that, so here is my
greylisting config for exim in full:

defer
    message        = $sender_host_address is
greylisted. \
                     Mail from $sender_host_address as
<$sender_address> to \
                     <$local_part@$domain> is delayed.
\
                     Please try again in a few
minutes.
    log_message    = greylisted.
    !senders       = :
    !hosts         = : +relay_from_hosts : \
    !hosts         = : ${if exists
{/etc/greylistd/whitelist-hosts}\
                      
{/etc/greylistd/whitelist-hosts}{}} : \
                       ${if exists
{/var/lib/greylistd/whitelist-hosts}\
                      
{/var/lib/greylistd/whitelist-hosts}{}}
    !authenticated = *
##    !acl           = acl_whitelist_local_deny
      domains        = +local_domains :
+relay_to_domains
      verify         =
recipient/callout=20s,use_sender,defer_ok
      condition      =
${readsocket{/var/run/greylistd/socket}\
                       {--grey \
                       $sender_host_address \
                       $sender_address \
                       $local_part@$domain}\
                       {5s}{}{false}}

You need to install greylistd which is available from
ATrpms for Fedora. I had to create a few files
manually before it worked, namely that
/var/lib/greylistd should include:

states
triplets
whitelist-hosts

I can pass you copies of these files if you need them
(Debian creates them for you so I copied them over to
Fedora).

Also, keep an eye on your Exim panic.log to see if
Exim is complaining something.

tail -f <logfile>

is useful for this if you don't do that already.
CTRL-c to quit.

I found that Exim just carried on as normal if there
was a problem with the greylistd, such as the missing
files.

One caveat. There is some further config to do to
capture emails without an envelope sender, but the
config I saw only refers to it in passing and doesn't
say how to do it, but at least it's a start.

Hope that helps, sorry I can't solve your problem the
way you wanted to go, but this way seems easier...
