This is interesting.  Indeed, the message IDs you retrieved are still
available on mixmin, but note the dates.
The ones I to which I was actually referring had dates of Date: Fri, 13 Mar
2009 02:40:45 +0100 and Date: Fri, 13 Mar 2009 01:06:56 +0100 respectively.
Frell duplicated Message IDs!
They Subjects and payloads of these messages were indeed identical, but it
seems odd that Frell would duplicate the IDs.  Well, I guess not *that*
odd, but it doesn't really explain why the latest messages with those IDs
were displayed on other servers which also have the older IDs on their
servers.  Bottom line is it looks like mixmin handled these messages
correctly.  I created this condition accidentally out of laziness, but if
somebody had created this condition with intent to spam or flood mixmin did
its job.

This problem may have been occurring for a long time and I just didn't know
it.  With the modifications I've made, I'm sure it won't be an issue in the
future.

Thanks.
I think this ticket is closed!
