evolution - filter mailboxes for duplicates - wish

Thanks for your report, this is known upstream: http://bugzilla.gnome.org/show_bug.cgi?id=253244

My evolution just duplicated 500 mails in a folder, by its own, while I was dragging a message from inbox to another folder. Being able to delete duplicate messages in a folder is really needed here. KMail was able to do it for years already.

any news for this feature?
there is a possible package for fedora http://kojipkgs.fedoraproject.org/packages/evolution-remove-duplicates/

similar/duplicate problem upstream https://bugzilla.gnome.org/show_bug.cgi?id=587011

sorry I cannot remove duplicate email automatically.
Where is this feature?

When using filters I can get incoming and outgoing emails to the appropriate folder automatically. However, Evolution insists on leaving a copy in the 'Deleted Items' folder. When I 'expunge' the Deleted Items folder all emails that have been deleted via a filter remain in the Deleted Items folder.

As far as I can see what appears to be happening is:-

Initially an email is brought into the main Inbox or Sent folder, then the filter applied, then the email moved to appropriate folder and finally the original in Inbox or Sent 'deleted' by sending it to the Deleted Items folder. this results in two copies on the system. One in the filtered folder, one in the Deleted Items folder. This duplication may be why it cannot be 'expunged'.

This is very messy and deserves more than a 'wish list' status. It is a bug! (or is it a switch-able feature that I am not aware of!)

Evolution 2.30.3
Ubuntu 10.10 AMD64
All updated from repos as at 14:00hours GMT Tuesday 23rd November 2010

There are plenty of reasons to get duplicate messages in any mail client, so please add the feature to get and remove duplicate messages.
The existing plugin "evolution-remove-duplicates"(http://ubuntuforums.org/showthread.php?t=384338) is not compatible with Ubuntu Maverick.
A model could be the "Remove Duplicate Messages" Thunderbird plugin (https://addons.mozilla.org/fr/thunderbird/addon/956/)
Evolution is powerful and misses this basic feature.
Please add this feature.
Thanks.
