So, you're passing just the message headers through SA?

Using a milter doesn't magically mean that you haven't received the
body of the message yet, it just means that a third-party extension to
Sendmail is allowed to review the message before Sendmail acknowledges
receipt and attempts delivery to the next stage (procmail, relay,
whatever). You've already spent the time and bandwidth and system
resources to receive the entire message and process it through SA.

So: why not save the resources consumed by receiving and processing
the entire message *multiple times* (because legitimate messages will
have to be almost completely transmitted at least twice in this model)
and use an existing tool (greylist-milter) to do the greylisting early
in the SMTP exchange?

What nuts do with guns is terrible, certainly. But what evil or crazy
people do with *anything* is not a valid argument for banning that item.
