Hi,
I'm using OpenBSD spamd before postscreen. I scripted a log tailing script
which checks any new connection to a few rbls and if it's not on them I
whitelist the ip, bypassing further greyfiltering.
After that postscreen gets to deal with whatever comes next. Now incase

I think you have a point there. Let's see what happens. Maybe later on I

BTW how can I read this dbase?

Anyway. No worries, I'll check the code and see what I can come up with.
It's just my silly wish to torture spambots a bit.
