I'm *delighted* to see that someone has done this! Thanks guys. :)

Can we run the PRDR ACLs _after_ the DATA ACL, with the DATA ACL having
access to a variable which indicates that PRDR is in use (so folks can
choose to not reject immediately)?

I'm thinking that virus and spam scanning should happen _once_, first,
and then per-customer decisions are made based upon preference
information, with the resulting scores, so that some reject, some route
to a spam mailbox server, some just accept, etc.

That's the normal use-case, I think, so we should have a singleton scan
available to set $acl_m_* variables which can be used for decisions in
the PRDR ACLs.

Does this make sense? Or am I being an ignorant bikeshed painter?

(I haven't looked at the code, just skimmed the experimental
description).

I'm thinking that if we're happy with this, I should really work to find
time to cut a release soon after it goes into mainline.

So if anyone else has fixes for 4.82, now is the time to get them in.

(I'm working at a start-up and really don't have time to work on the
DNSSEC and lookup stuff I wanted to do; mind, I'm in SF right now and
flying home tomorrow, I *might* be in the mood to hack on the plane).
