What is the issue here?
How far back in time is the runner expected to remember?

Forever? :)

What I'm thinking is that early in the process we'll register every Message-ID
we've seen (or maybe it should be every one we've accepted) in the message
store.  Then the LMTP server can check the message store before it accepts any
new message.

I should note though that I've tried several branches in the (distant-ish)
past to implement this, and there are lots of tricky details to work out,
especially around some assumptions in the test suite.

I marked it High because I think it should be tackled once more before 3.0
final.

Cheers,
-Barry
