100s of duplicates after transferring 4 accounts from one provider to another. This smart little addon found them. Great Tool!

Cumple muy bien su función y es fácil de usar.

One of the "Must Have" addon Rated 5 out of 5 stars

I can not thank developer enough for making such a useful addon. Only if there was a way to operate this addon through windows command line/cmd.exe, it would make life much much more simpler

Command-line operation

You are possibly looking for something like mbox-tools:
https://github.com/np/mbox-tools
which operates on Thunderbird's (highly dated) mail storage backend. I'm not sure if mbox-tools has dupe culling, though.

Version 0.3.9b - icons look good :)
But I cannot switch on search in special folders in option - any mark do not do it.

Works perfectly Rated 5 out of 5 stars

The key to making this add-on work perfectly is to adjust the comparison criteria so that you know the messages that match are truly the same as each other in spite of having small differences in the body, which can happen. Thus the number of lines could be SLIGHTLY different and the size might also. For example, you might have an extra NULL in one, or an extra <LF>. Make sure you have enough criteria so you are confident of the found matches. The tool is great.

Does the job, quickly and accurately Rated 5 out of 5 stars

Like the title says. Does what it's supposed to, and more quickly than expected.

Update of prior review Rated 4 out of 5 stars

After some experimentation, resolved the problem I experienced in my previous review. And as a result, upped the rating to 4/5 stars. Not 5 stars as that problem and its work-around are not obvious.

The problem is that when you first install the addon and try to use it (either before or after restarting Thunderbird 17.0.x), it does not detect POP account "Trash" folders properly.In the Duplicate Messages Deletion window that appears after detecting dups, at the bottom are the choices "Delete permanently" and "Move to...(drop down list of folder choices)". "Move to..." defaults to "Trash". But leaving that choice alone, it will not properly detect the Trash folder on the account you are detecting dups on, unfortunately. Which means dup messages get permanently deleted, even if you don't want them to be.

To avoid this problem, you first have to open the drop down list beside "Move to..." and manually select the Trash folder for the account you are detecting dups on. Then and only then will your dup messages get properly sent to Trash. In the future it will remain properly selected, so you only have to do it once. Don't know if you have to manually change it for every account you are working on, but I do so to be safe.

This is still a problem and still needs fixing, but at least there is a way around it until its fixed.

EDIT: replying to the author response below. Thanks for the response, but unfortunately you totally misunderstand what the problem is. I elaborated more in my original review linked to at the bottom of this post; might want to look at it.

The problem has _nothing_ to do with "detecting duplicates in trash". The problem is when detecting duplicates in the INBOX of a selected account, the "Move To..." selection defaults to "Trash" (of that account). And by default, it doesn't actually move your messages to there as you would expect. It instead wrongly permanently deletes them.

To work around this problem, you must manually select the "Move To..." folder (Trash or otherwise) for each account in the drop down list.

If you don't do that and instead rely on the default "Move To...Trash" location without adjusting anything manually, your mail gets permanently deleted out of the Inbox when you didn't want it to after pressing "OK". That's the problem.

It is 'proper' not to find dupes in the Trash

Practically all users expect Trash folders to be skipped when looking for duplicates. This is both because dupes are usually deleted to the trash (incl. manual deletion), and because, more generally, whatever's in the trash is already not really part of your mailbox, it's deleted-but-undisposed-of. So, it would certainly not be a good idea to change this default behavior.

I understand you might like/expect something different, but you must recognize you're in the minority. For you (and others), there's the preferences dialog with which you can change such settings.

Just great! Used it to split messages I already had transferred in an aborted bulky transfer. Could resume just fine! :)

I'd donate if the donate functionality wasn't broken. After I fill in the amount and comment, the main page is grayed out but no paypal page comes up....

This add on is a life saver. I depend in it a lot.

It will be awesome if it works automatically every period of time

Phenomenal! (Plus one Suggestion) Rated 5 out of 5 stars

Saved my life, thank you _so_ much.

One suggestion. In Options, comlement the ability to compare "Number of Lines in Message" with the ability to compare "Number of Lines in Message _Body_". That way when we have two messages with a different number of headers, we can ignore the difference.

Very useful Rated 5 out of 5 stars

Very useful tool. Thanks!

One detail: the selection dialog proposes to move the deleted copies to Trash. However, I am using several accounts, and therefore several disctinct Trash folders. I was surprised to find al the deleted copies in the Trash of my Local Folders. Is it normal?

Yes.

OK I see, at least for "size" which is what I need. Thanks

A really great extension that must have been a lot of work to create. Rated 5 out of 5 stars

This extension is definitely one of the best out there. I've just migrated from Thunderbird to Postbox and was disappointed that it isn't compatible :-(
