Milter-greylist

Well yes, That's a problem.
And besides: I do not think greylisting at the data is a wise thing anyway:
1. If you tempfail after data stage, the sender is more likely to treat
it as a permanent error
2. A lot more computing needed (you have to receive the whole message)

Once you are in the data stage, I would employ some spamassassin to
handle it.
