Why yes, I know how SAV handles greylisting.

When SAV receives a temp failure, SAV returns a temp failure. A real 
mail server will try again later which will cause SAV to verify again 
when the sending server retrys. This works just fine. However, if you 
run greylisting too, this adds a double delay on th delivery of the email.

I can live with that.

Life should not be a journey to the grave with the intention of arriving safely in a nice looking and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming, "WOW! WHAT A RIDE!"
