I'm not sure any of that matters since the problem is with installing a 
self-contained daemon which should just run.

I have discovered an alternative method that works with MySQL and 
doesn't require any kind of daemon.  The reason I don't prefer it is 
that it doesn't have an automated whitelisting method; I'll have to 
write a program to add whitelists.

What would you need/want to know about our servers?  They're fairly 
generic 1U systems running CentOS4.  The fact that the RPM installs 
without any kind of prereq error says it should work.  Or not?

The MTA is exim.  That can't be changed, as the servers are running the 
DirectAdmin control panel (http://www.directadmin.com/), which requires 
exim.  DirectAdmin is a wholly-contained compiled C++ program requiring 
no dependencies.  But it's intimately connected with the way exim 
works.

Once I get greylisting working, I want to greylist selectively, if 
possible.  First I just want to get it working <smile>.

And once it works for me I want to make it part of the exim.conf file I 
write for DirectAdmin servers, so others can use it.

What other kind of "setup decision things" should be considered?  The 
version of Python should be the only dependency, but the RPM shouldn't 
have allowed the installation if I'm not running the right Python 
version.

$
</snip>

After the failed startup (please refer to my log snippet in my previous 
post), grepping the ps output shows python2.3 running greylistd...

<snip>
$ ps waux| grep grey
104      11911  0.0  0.3  8936 3932 ?        S     2006   
0:00 /usr/bin/python2.3 /usr/sbin/greylistd
jlasman   6485  0.0  0.0  4392  676 pts/2    S+   05:36   0:00 grep grey
$
</snip>

So maybe it is running and I should just try to use it?  But I'd think a 
daemon should continue to run.  And I don't want to break my incoming 
email.  I'm creating a testbed to try it.

Of course, for many hours.  But how do you know I'm smart?  Most of the 
time I don't feel that way myself <smile>.

Anyone's help is appreciated.

Thanks.
