Are you sure that you're actually seeing *rejects* and not *refusals*?
I've never heard of the problem that you're reporting.
Here's an example from newsfeed.stanford.edu. Note that it's almost all
refusals (which are normal), not rejects. The rejects that are there are
generally for groups that aren't wanted:
Server Offered Taken Refused Reject Miss Spool %Took
TOTAL: 54 4275671 1144030 2649616 58509 10305 262353 26%
In my incoming statistics, you can see that I have very few duplicate
articles incoming (and I peer with plenty of INN sites):
Sites sending bad articles:

TOTAL: 39 1038258 954001 0 12571 101 386 0 0 71199

Can you supply some detailed statistics and log lines for this?

I'm not seeing this in a Google search. Could you point me at some

Please send questions to the list rather than mailing me directly.
<http://www.eyrie.org/~eagle/faqs/questions.html> explains why.
