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. } As I understand the process, Listserv accepted the first FAQ and passed it } to the list membership. As part of the posting process it added a CRC } calculated from the body of the message to what I assume is a circular } queue of 90 entries. Why 90? Because I set my list to accept 90 } messages per day with the "Daily-Threshold= 90" statement in the list header. } This normally defaults to 50, but this list/Usenet group generates on an } average day about 75 messages. 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 } it is a duplicate realistic? Does this happen often? I would think that it } would not be much of a problem unless the FAQs were the only thing posted } to a list (is this the case for the SCIFAQ-L list?).
