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.
