Rusty,

Since you have the most complete set of questions...  :^)

I just finally got tired to seeing all the "why am I getting duplicates...?"
posts; asking the same question over and over does not solve the problem... you
gotta dig deep[er]...  :>

I didn't feel the count mattered 'cuz a computer can make the same mistake
forever without complaining; fix the cause and it'll behave regardless of
counts...

Yes; just pointing out that it was at the core of the issues.

Correct; though if we can reduce the problems in the meantime...  However, the
following ones require a smarter set of rules...

<self> was just to indicate that the sender was mailing a copy back to
themselves to push a copy of their posts through their filters for filing.

This is where my post got caught...  though in my case, I sent:
  To: cooker...
  Cc: expert...

Which means that when you think you are cross-posting, the list server simply
sends both copies to the "To:" list; I missed this variation in my original
post.

This *might* explain those that had no apparent reason for replication... :?

I'd be surprised if we need to go there...  I've gotten a response from Denis,
the maintainer of the rules and have already replied to him...  Hopefully we can
get to the bottom of this RSN (real soon now)...
