Greylisting has nothing to do with spamassassin, and this is not an  
either/or situation, just like RBLS are not a replacement for  
spamassassin.

On my system, about 18-20% of the grey listed email eventually gets  
delivered. Of the 20% that gets delivered, about 50% of that is  
spamtagged by SpamAssassin. About 80-85% of the connections to the  
server are rejected outright (RBL, invalid hostname, etc), before  
greylisting has a chance at the message.  If greylisting was in front  
of our RBL and header checks, it's percentages of ultimately rejected  
spam would be much higher.

This is our music from the bachelor's den, the sound of loneliness
        turned up to ten.  A harsh soundtrack from a stagnant waterbed
        and it sounds just like this. This is the sound of someone
        losing the plot making out that they're OK when they're not.
        You're gonna like it, but not a lot.  And the chorus goes like
        this...
