What I do, because spammers target the lowest MX server, is to set-up 
the last MX as the same server as my highest MX.  This has been quite 
successful to date when I've been using in-line SMTP spam scoring (at 
the moment I'm not - I change my config my often than people have hot 
dinners).  That plus tarpitting does have the desired effect and 
generally puts off those spammers doing dictionary attacks early in the 
attack stage.

As for Greylisting - having dealt with it as an end-user and as an admin 
it's far more trouble than it's worth.
