Since greylisting is to keep spammers out, who don't retry at all, any 
delay greater than 5 seconds should be good enough.

With that said, I keep mine at 1 minute.  I had it on 5 minutes for a 
long time, and after the change, I haven't seen any more spam than I did 
before the change.  The benefit now is that the delay on some good 
messages has decreased a lot.
