There are milters around that do it. Dont have a URL because we opted to 
not greylist.

It comes down to how busy your servers are, and how many you might have in 
the farm. if you run a decent use mail server, i'd forget it. do you 
rteally want a queue that banks up for tens of thousands because it will 
not send on for 10 mnis or whatever.

I've heard it delaying local sent mail up to 4 hours on a few decent sized 
ISP's, using it with varying MTA,s sendmail, qmail and postfix, all were 
as useless as the next with greylisting with their use loads, hence none 
of them use it nemore :)

But if you get 100 messages a day, I guess it wouldnt make much differnce
if you got mail now or in another 10 mins or so.

Also if you run mailing lsits  forget it, youll have so many complaints 
u'll regret even knowing what greylisting was
