[CentOS] problems with greylistd

I'm using CentOS 4.4

<snip>
# cat /etc/redhat-release
CentOS release 4.4 (Final)
#
</snip>

I downloaded and installed greylistd as follows:

greylistd-0.8.3.2-7.el4.at.noarch.rpm

from:

http://riksun.riken.go.jp/pub/pub/Linux/atrpms/rhel/4/en/i386/RPMS.at-stable/

I installed it without problems.

<snip>
# rpm -Uvh greylistd-0.8.3.2-7.el4.at.noarch.rpm
warning: greylistd-0.8.3.2-7.el4.at.noarch.rpm: V3 DSA signature: NOKEY, 
key ID 66534c2b

#
</snip>

But it doesn't run <frown>.

I start it using "service greylistd start".  I'm presuming that should 
work, as all the files seem to be in place for it to work.

<snip>
# service greylistd start
Starting greylistd:                                        [FAILED]
#
</snip>

The message in /var/log/messages is decidedly unhelpful; all it tells me 
is that the program started and then stopped:

<snip>
Dec 31 19:43:53 da12 su(pam_unix)[11890]: session opened for user 
greylistd by jlasman(uid=0)
Dec 31 19:43:53 da12 su(pam_unix)[11890]: session closed for user 
greylistd
Dec 31 19:43:55 da12 greylistd: greylistd startup failed
</snip>

Any ideas as to what may be going on?  Or where I should look?

Or if there's easily installable source-code available?

Thanks.
