I've been looking into ways of improving our spam filtering.  Currently 
I'm running postfix with amavisd-new (spamassassin and clamav), and saw 
an article on greylisting using postgrey.  Turns out there's a port for 
it already in FreeBSD.

I am still googling for info, but as I understand it the policy will 
inject the message to another queue for postgrey to evaluate?  If this 
is true, what happens if I install it while still running the 
postfix/amavis solution, which is also a double-queue system for 
evaluation of messages?  Will doing a make install for postgrey damage 
the installation we currently have in place and working?

Anyone else running postgrey with amavis on postfix, on FreeBSD?  I'd 
appreciate any feedback/experiences people have to offer.
