We've been getting duplicate messages lately. Here are the various
reasons:
- when we switched from 2.9 to 2.10, the format of the history
file changed. I didn't remake the history file, hence it had
entries such as "sri-arpa.3087". When the same article came again,
its ID was "<3087@sri-arpa.UUCP>", and the duplication wasn't detected.
- Somebody's playing games with domains. For instance, we got the
Toy window editor article twice. Here are diffs of the 2 articles:

Finally, sri-arpa seems to be having trouble with their clock.
We've gotten several messages (sri-arpa.3181 and sri-arpa.3081)
that appear to have been posted several days in the future!

Suggestion to combat the domain-specification problem:
Have inews look for ".ARPA" or ".UUCP" (actually, to be precise, any
"." after an "@", right?) in the message-id. If it's there, remove
it. That way news will reject duplicate articles with different
domains (which will happen anytime sri-unix gateways to arpa and it
somehow filters back).
It shouldn't be difficult, just a few lines in inews's history-lookup.
