None.  But one still wonders why anybody would consider *running
SpamAssassin* anywhere but in the MTA (or in the pipe to the delivery
agent, if milters aren't supported as is apparently true for Courier)
an advantage.

You can do that with Henstridge's code, but IMO it's an ugly kludge
compared to running SpamAssassin early and configuring it to report
special features for use by the SpamDetect Handler in Mailman, etc.
They could be given default scores of 0.0 if they can't reliably be
used for scoring except for certain addressees, but they'd still be
reported if their rules are triggered.

In your case you'd be running it in maildrop, which presumably means
you know which addressee(s) is (are) being delivered.  It should be
possible to give that information to SpamAssassin (SpamAssassin knows
on which user's behalf it's being run, although I forget the details)
and configure rules conditional on that information.  I don't see why
this would be enormously harder than than if SpamAssassin were running
in Mailman, and it would have the advantage that rule dispatch would
be configured in one place.
