As I remember (but remember whose memory we are talking about :-) - I had 3 lists - those known to be spammers, those known to be ok, and anybody else. (Ok, so the 'anybody else' wasn't actually a LIST, it was anybody not in the first 2 lists) Known spammers got some huge delay (I think I finally ended up with 24 hours!), known safe senders got zero delay, and unknown got a few seconds (or maybe I made it zero, I don't remember). So non spammers got either zero or minimal delay. If I can remember, I'll see if I still have that config file somewhere, cause now you got me curious! I should mention that there IS one 'small' downside - if you get ALL your internet sockets tied up with spammers then you cannot receive (or send) email (or do anything else network-related until one of the sockets frees up). I don't think I ever hit that limit, but then I only do email for my family...
