	Not quite true ed, 

	spamd will look like a tarpit for the first 10 seconds or so
when greylisting because many spammers drop connections immediately
when they see such behaviour. no real MTA gives a damn if the
connection is slow for 10 seconds. 

	basically forces spammers to deal with tarpits - otherwise
they never get through - when they don't get through it's fine, they
go bother someone else.
