Oops.  I was looking at another list that claimed to be "authoritative" 
and all it had were some nasty perl implementations.  This one look 
promising.  It doesn't do the triplet thing, but it is simple and his 
example shows that it works with qmail+vpopmail, which is a requirement 
for me.  It also does not entail patching qmail:


This one might be promising as well:


I am looking at moving vpopmail to using pgsql for the backend instead of 
mysql because mysql keeps biting me in the ass on FreeBSD.

Thanks for pointing me to the puremagic site, not sure how I missed it. 
I'm going to start fiddling with cqgreylist on my personal mailserver this

Interesting, but my mind is too full of other junk ("jack of all trades, 
master of none").  I have trouble right now going back and forth between 
mysql and pgsql.  :)

Thanks for the input, it's very much appreciated.
