If it ties up your SMTP daemons, postscreen can deal with them,
but for this you need to turn on an "after-220-greeting" test, for
example

    postscreen_pipelining_enable = yes

And perhaps:

    postscreen_pipelining_action = ignore

Every 30 days by default, an SMTP client will spend one SMTP session
just to renew its whitelist status, and gets 4xx replies for attempts
to deliver mail (see postscreen_pipelining_ttl parameter documentation).
The next time the client connects, it will be allowed to deliver mail.

You'd need to use memcache if you want to share the postscreen
whitelist among multiple MTAs.
