Greylisting is still very effective. However, it should
be considered as "another layer of defence". Proactively
grab statistics for hosts that bypass Greylisting. This
is very easily done if using SpamAssassin v3.x. Also,
collect statistics on the hosts who have the most
unverified/unretried triplets and permanently blacklist
those networks aswell.

Dont wait till the spammers learn to retry, start
collecting all their networks ranges today for a
spam-free tomorrow. :P
