I've received one reply so far of a useful nature, ws well as permission to
share the email. In the interests of the many people whom have commented on
the problem of duplicate articles, it is reproduced in edited form below.

"Are you running dbz ?"

"... inews has error checking to reject duplicates but this depends upon dbz
 if you are using it. And, dbz doesn't always find the article id when it
 does, in fact, exist in the history file. I had as many as four copies of
 the same articles as a result. From a number of comments, I suspect that
 the use of dbz is fairly widespread, unfortunately. I did a local poll of
 sites connecting to this one and found that 100% of the ones that had
 multiple news feeds and were running dbz had duplicate articles. Since junking
 it, I have none. Further,I was sending the duplicate articles to a downstream
 site also running dbz and they were duplicated on his system with this one his
 only feed."

":-) As I am sending this email, you may certainly distribute it as you
 see fit. I do hope this is of some assistance -"
