[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 Preparing... ########################################### [100%] 1:greylistd ########################################### [100%] # </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.
