# When I went back and checked on the archive, sure enough. These
# messages have identical MessageID's on them in the headers, BUT, the
# messages are different. They're not duplicates. So, a) how in the
# world can one get email with identical MessageID's in the header
# (spanned across several days sometimes), and b) how in the world to
# solve this problem now?
Was it obvious from the other message headers that they came from
the same site ? Or did a memory problem mess up a mailer and a
software glitch occur ?
You will not be able to solve the problem for the world. There are
just too many screwed up MTA implementations and misconfigured
mail servers. You'll have to make the decision for your site.
What do you require locally ? Using the .hmrc directive
discard_dup_msgids = 0
hypermail will not discard messages duplicate msg-id: headers. By
default it does. The only way hypermail could fix it would be to
basically 'diff' the two messages when a duplicate is encountered.
That's a good deal of overhead that would slow things down with
large archives.
When I've encountered misconfigured mail software I have sent
a message to the site admin of the offending site. That has
helped a couple get things corrected but...
Probably not the answer you were looking for. :)
