Don't do this. Greylisting should not be used to punish real MTAs. Use
Greylisting with automatic whitelist so only the Spam-Bots get cut
away and let already know MTAs pass by. Works exceptionally well here,
the Bots go away after 2-3 tries and 90% of the sending MTAs are on
the whitelist after some time.
mtpolicyd can call greylist when ip is on dnsbl or simply not on dnswl, ips
that is on dnswl will not be greylisted so, readding docs in mtpolicyd
seems to show it can self do the greylist part, but i have not yet seem it
works, but it can use another policy server called from mtpolicyd
else try sqlgrey where its possible to have more fine grayned configs pr ip
/ hostname / what ever :)
