I will go with erik on this. I am using the standard smtpd with -D and the greylisting, and also a modified validateserder which probably qualifies as an earlier incarnation of erik's (he sent me the code before nupas was finished and I hacked it a bit).
I get 1 or 2 spams a day. I plan to try nupas as soon as I get a timeslot. -Steve
