Description Keith Ivey 2003-10-28 16:45:51 UTC 
I'm attaching four messages received yesterday and today.  Three have identical
Message-Id headers.  The fourth isn't a problem because the message ID is
different, but I'm attaching it anyway because the part of the message ID before
the '@' matches the others.

I don't think this is the only time this has occurred.  I've suspected it for a
while when I try unsuccessfully to learn messages that shouldn't have been
autolearned.

Hmm... I suppose it might make sense to have a test to see if a message ID
already exists in the ham/spam learn DBs. Then spammers wont do it....

it'd be interesting to see, but I doubt it would work very well.
I receive multiple copies of the same message whenever someone responds
to a mailing list post I made.

this issue came up before, and we decided it wasn't a big enough issue
to deal with.  perhaps we should use the same logic as "no message-id",
which does a sha1 hash of certain message characteristics.
