removing duplicate mails

removing duplicate mails

[Mattias Rönnblom]

Hi,

I have a number of duplicates in my mail groups, which I would like
to delete. But unfortunatly there weren't marked as duplicates when
they were fetched from the IMAP server (my nnmail-message-id-cache-
length was too small). Is there some way of rechecking all mails
in a group for duplicates?

I'm using the nnml backend, if that makes any difference.

Thanks,
        Mattias

Do the messages still have identical Message-IDs?  If so, you can
probably do something by setting `gnus-suppress-duplicates' to t,
enter the group with `C-u RET RET'.  `gnus-dup-list' will then
contain a list of all duplicated messages, and you can write a simple
function to delete these messages, leaving just the suppressed
messages left.  Then, the next time you enter the group, there'll be
only one copy of each message.
