Yeah, sure enough.  You're using mutt?

The mbox "standard" is that any line beginning with "From " denotes a
new messages.  So a diff of those two mailboxes shows things like this:

 Return-Path: <removed>
 Delivered-To: <removed>
+X-Spambayes-Trained: spam

I think spambayes is actually doing the right thing here--it's taking a
weird mbox and un-weirding it.  I think Tim Stone might be working on a
generic message store thingy: Tim, would that eliminate the need to
rewrite mailboxes altogether?

But David, if I were you I'd start trying to hunt down what's creating
those duplicate headers.  It might be some sort of wonky procmail recipe
that just writes out headers and then drops through, but that's just a
shot in the dark guess.  Heh, maybe it's hammiefilter <0.7 wink>
