spamd greylist and stutter/delay

[Will H. Backman]

I have spamd get up in a simple greylist mode, but I left the default 
/etc/spamd.conf file intact.
I'm not running spamd-setup.
By default, spamd is stuttering for 10 seconds, but watching 
/var/log/daemon, I also noticed that connections from spews and other 
lists are lasting for over 400 seconds.
Does spamd do anything else with /etc/spamd.conf besides set up white 
and black lists?  Does this file effect the stutter or delay of connections?

By the way, spamd really does a great job.
