See section 6.3.11 in the Gnus manual:

| 6.3.11 Duplicates
|
| If you are a member of a couple of mailing lists, you will sometimes
receive two
| copies of the same mail. This can be quite annoying, so nnmail checks for
and
| treats any duplicates it might find. To do this, it keeps a cache of old
| Message-IDs--- nnmail-message-id-cache-file, which is `~/.nnmail-cache' by
| default. The approximate maximum number of Message-IDs stored there is
| controlled by the nnmail-message-id-cache-length variable, which is 1000 by
| default. (So 1000 Message-IDs will be stored.) If all this sounds scary to
you,
| you can set nnmail-treat-duplicates to warn (which is what it is by
default),
| and nnmail won't delete duplicate mails. Instead it will insert a warning
into
| the head of the mail saying that it thinks that this is a duplicate of a
| different message.
|
| This variable can also be a function. If that's the case, the function
will be
| called from a buffer narrowed to the message in question with the
Message-ID as
| a parameter. The function must return either nil, warn, or delete.
|
| You can turn this feature off completely by setting the variable to nil.
|
| If you want all the duplicate mails to be put into a special duplicates
group,
| you could do that using the normal mail split methods:
| (setq nnmail-split-fancy
| '(| ;; Messages duplicates go to a separate group.
| ("gnus-warning" "duplication of message" "duplicate")
| ;; Message from daemons, postmaster, and the like to another.
| (any mail "mail.misc")
| ;; Other rules.
| [ ... ] ))
|
| Or something like:
| (setq nnmail-split-methods
| '(("duplicates" "^Gnus-Warning:")
| ;; Other rules.
| [...]))
