It would be very nice to have and useful information.  Especially now  
that I am impatiently watching my tables grow and waiting for emails  
that I have seeded from many other sources, I am far from comfortable  
with pfspamd but seeing that I have received almost no spam since I  
started the test, is currently compensating.  I would give postgray a  
try but don't have a server running postfix right now and don't have a  
lot of time and for now am going to set up pfspamd on all unless I  
find some major issue.

Thanks again for all the useful information.
