[Exim] Delay 220 greeting to reduce spam?

Is there a way to make exim delay giving the initial 220 greeting for an
arbitrary amount of time (say, 40 seconds or so)? The idea is that most
spamware will give up after 30 seconds (most are quite impatient from
what I've read) and move on to the next host. Others that have
implemented it on their MTAs have seen good results with this method.
