Important distinction: I've never sent your list anything, by hand or
automatically.  I only send to USENET.
 
That incident was indeed a finger problem on my part, but it still begs
the question of whether a LISTSERV should ever bounce a duplicate back
at a USENET-origin posting.  The SCIFAQ-L incident is much different.
Una must have his checksum period pretty long to catch Detweiler's
postings.  I don't know what his interval is, but I presume that it's at
least a week.  Few FAQs have that short an interval, but a couple do
(they have usually been set that low after experimentation with a
specific group.  I had to make the wiring FAQ go out once a week because
the repeated Qs that were in the FAQ got ridiculous).  Certainly not 13
parters like L.  Detweiler's.

} to the list membership.  As part of the posting process it added a CRC

} queue of 90 entries.  Why 90?  Because I set my list to accept 90

This sounds like a good setup.  Actually, I'd personally suggest that
you set the checksum count up much higher.  Come up with a minimum acceptable
repeat time (perhaps a week or more) that your readership sees reasonable.
But don't do this until Eric fixes the bounce-usenet postings problem.
 
} Are we arguing about rejecting the posting after a month because

} to a list (is this the case for the SCIFAQ-L list?).
 
This is my impression.
