Removing duplicate emails in Mail

While attempting to back up my Gmail -- which is at capacity right no -- I accidentally reset the POP setting and downloaded all my mail again.
So now I have 160000+ emails in my mailbox in Mail. I would like to weed out the dupes, and after a bit of Googling, found Mail Scripts (http://www.versiontracker.com/dyn/moreinfo/macosx/16217) and started running the Remove Duplicates script.
Everyone said it was slow, but after leaving it running all night it had found only 119 duplicates! Is there any other program that will remove the extra mail, or there some way to shorten the process? It seems like my mailbox is just too big for this script to handle.

Just a thought, but take a look at your Mail Menu "View", select columns, then make sure it has both Date Received and Date Sent checked. Then compare duped messages and see if the date/time is the same on both. I haven't had this problem, but if the Date Received is different on the second copy of the duped email, you might be able to sort on Date Received and mass-delete the dupes...

How to remove duplicate emails in Mail

Does anyone know if a good app that works in Lion that will help me remove duplicate emails in Mail? There are some options on the web that I've found but they don't seem to work with Lion.

I have found a very satisfactory solution to eliminating my duplicates in Apple Mail, which is to stop using it and switch to Thunderbird.
There's lots that I like better in Apple Mail, but Thunderbird is light-years more flexible in managing your email than is Apple Mail, because Thunderbird is an open platform with excellent Add-ons available, which include the nifty Remove Duplicate Messages: http://bit.ly/tbird-dups. It is stupid that Apple Mail hides duplicate messages in the background & won't allow users to search and destroy them. Frustrating!
As a prologue to that, you need the TB import export Add-on: http://bit.ly/tbirdimportexport
Managing my mail locally on my Mac was a huge project for me, involving integrating tens of thousands of emails. Mail was from gmail, yahoo, and many years of Outlook PST files.
Now that the project is complete, I'm very happy with Thunderbird to manage my email archives. Though I actually would prefer the Lion Apple Mail interface for day to day use, it just isn't flexible enough.

Remove duplicate emails??

Every once in awhile something inside of mail triggers a re-download of mail from the server. It happened today and down I have 10,000 +/- duplicate emails all marked as unread. Is there anyway to remove duplicate emails from my download email folder?
bill

Same problem, only one of four accounts (POP) acts this way, and is reloading, and re-reloading, and re-re-re (you get the picture) mail from this account going back to June 07. All marked unread,up to almost 2k of these so far. Running OSX.4.10, dual 2ghz Powermac, 4gb ram, no recently added software.
Thanks!

Is there a way to find and erase duplicate emails in mail.app?

Mail.app does not have this possiblility acc. to Apple. There are Scripts but not provided by Apple.
A solution can be to use third party software but I prefer Apples own software so have to wait until there is an update.

How to remove duplicate messages from Mail in Mavericks (POP)

Hello
I'm having some significant problems with Apple Mail, and despite having researched widely, I haven't been able to find a solution yet. Here is my tale of woe...
My set up is that I use Mail with 5 separate accounts, downloading all messages using POP. I keep all my mail so that I have a permanent record of all conversations, going back more than 10 years - this is about 250,000 emails. I'm running the latest version of Mavericks on a 2010 MBP. I have no intention of moving to IMAP - I need to keep a local archive of all my mail.
A few months ago I was having problems with Mail being very slow to load and search emails. I decided to rebuild the mailboxes, but afterwards discovered that thousands of messages in the inbox of one of my accounts (and some of the sub-folders) had disappeared. Once I realised I tried to go back to a recent Time Machine back up, but, for whatever reason, that part of the back up hadn't worked properly and I was unable to recover the previous status. Ileft it while I decided what to do, and had time to deal with it.
The last 2 years worth of emails on that account were still archived on gmail, so last week I decided to try redownloading the whole lot (something like 72,000 messages), and then uplanned to use one of the scripts I was aware of to remove the duplicates to the trash, and then remove any duplicates in the trash forever. That ought to mean I at least had an archive of the last two years of missing messages, even if I had no record of which ones had been flagged or replied to, etc.
The downloading took about 24 hours to complete, and I now have almost 70,000 messages in the inbox of that account. However, I hadn't figured on two things:
1. Mail 'hides' duplicate messages, meaning that all of the messages I've downloaded are showing as unread, and I can't differentiate the ones I already had in my Inbox, and the new downloads. When I click on those apparently unread messages I can see if they have been replied to or forwarded, etc, but there's no obvious way for me to remove the ones I have already dealt with to the trash, without going through them all manually, which is clearly impossible.
2. The scripts I'd found for removing duplicates don't work. Andreas Amann's Remove Duplicates script doesn't work under Mavericks, and he has abandoned the project. I've also tried the remove-duplicate-messages.scpt made by Jolly Roger (http://jollyroger.kicks-***.org/software/), and while it *sometimes* works on individual subfolders on my Mac (but as far as I can tell removes the duplicate in that folder, rather than the newly downloaded version), mostly it doesn't work at all - it creates a 'Remove Duplicate Messages' folder on my desktop, a log inside it and a folder for removed messages, but nothing appears in the duplicates folder.
So, I'm left in a position where I have 70,000 apparently unread messages in my Inbox, a massively bloated Mail library (which has pretty much doubled in size), a slow and unresponsive Mail program. I figure I have a number of options. Either I could abandon the last week's efforts and revert to the version of

How do I delete duplicate emails in Mail 6.2?

I imported emails from thunderbird, realising I have hundreds of duplicates. Have you any idea how to remove duplicates in Mail 6.2? I tried Mail Scripts but they are not working with Mac OS 10.8.
Thanks!

Are the duplicates in the same directory? One way to do this would be to use a UNIX shell script, which could compare each of the email files, identify duplicates and delete them.
If you are feeling adventurous, there is a thread in a forum (http://forums.devshed.com/unix-help-35/bash-script-to-find-and-get-rid-of-duplic ate-files-184849.html) that has a pretty interesting looking script at the end. It does and md5 sum on each file (which should always be the same for identical emails), and then deletes the second file. (Actually the deleteing bit is commented out, it just prints what it would do if you remove the '#' before the "rm".
The principle looks good - but I cannot vouch for it at all!
Cheers,
Rodney
p.s. PLEASE back up before trying anything.

Duplicate Email Messages Mail 4.3

Greetings,
I am running Snow Leopard 10.6.4 and using the built-in Mac Mail client 4.3. I subscribe to MobileMe and have my primary mail alias and second mail alias. I use server based rules to manage my inbox.
For the past few weeks, I've been getting duplicate email messages in my inbox.
I have googled this and most of the articles that come back are dated.
Has any one else experienced this?
It has been working fine for months.
I have tried rebuilding my mailbox and have not noticed a difference.
Thank-you,
Derrick

This problem just started-up for me, too. Same Mac mail client; Snow Leopard. I have no rules set. I have two imap accounts feeding the client; only one is misbehaving with the duplicate generation. Need a solution!

Sending Duplicate emails using Mail and mBox for mac

I have been sending duplicate emails inadvertantly recently. It seems it's when I use mBox for mac (registered copy) in Mail to use my Hotmail with IMAP.
I hadn't noticed it at first, but now I see everytime I send a mail I get 2 copies in my sent box. I can turn off the store sent messages on server option to fix it (but that's the whole point of having IMAP!!), or I can turn off mBox for mac and it also seems to work (but then I can't use IMAP!).    I've also tried on the same machine from gmail, and iCloud accounts (MobileMe), and I had no issue at all. I've also tried 2 different Hotmail accounts, and both of them send double messages every time I send.
I've searched for a loooooong time, and can't find anyone with a similar issue - but surely I'm not the only one? I think anyone still using a hotmail account will eventually install something like mBox for mac if they've gone Mac recently - as I have.
I checked the mail headers of the 2 mails, and they are quite different (masked where appropriate) -

I'm surprised I can't find anyone else with a similar issue. I've submitted a support ticket with mBox/fluent factory, but I'm still not convinced it's their issue, and possibly a Mail on Mac issue.
Does anybody have any suggestions? Thanks for your help!

@ Kokola
Great staff!!! MBox Fluent Factory is very poor app.
I was having problem with duplicated sent emails and cleaning up my inbox, sent items and deleting emails. Try to contact them via email for over 3 months and never got a reply!
I just used the suggested configuration and my Entourage (email app for MAC) is working perfetcly. I can visualise all my online folders now!
Thank you so much!
mBox never addressed the issue and the duplicated emails reached new levels of annoyance but the good thing is that Hotmail and Outlook.com finally rolled out support for IMAP.
Incoming Mail Server: imap-mail.outlook.com
Outgoing Mail Server: smtp-mail.outlook.com
http://windows.microsoft.com/en-us/windows/outlook/send-receive-from-app
No more duplication issues once you switch over, and no need for a third party (mBox)software to bridge the missing feature gap.

Duplicate emails in Mail with gmail

Hi, I keep getting multiple duplicate emails in my inbox. Even the one's I've deleted keep coming back. They appear across my folders and it's really frustrating as I'm unable to stop it. I've checked the discussions but cannot see an obvious solution (unless I'm looking in the wrong place) other than to disable my POP account in gmail settings, which I've done. Can anyone offer any help please?

Remove duplicate emails and mailboxes

I am moving emails from an old Mac to our new MacBook Pro. My wife has a LOT of mailboxes. It seems to me that when she imported her emails onto our old Mac, from an even older Mac, that mailboxes got duplicated. I think there are mailboxes and folders (with different names) that actually contain the same emails (or mostly the same) as other mailboxes and folders.
I've read some of the threads on the Apple Support Communities. I understand there is a script for finding duplicate emails. But will this only find duplicates within the same mailbox? I don't have this problem. I need to find duplicate mailboxes and duplicate emails within different mailboxes.
I am using Lion and Mail.
Thanks for any help

Removing duplicate emails

Hello all,
I have looked on the web but I cannot find any solution to my problem, 'How to remove duplicate mails from my mailboxes'.
Most are empty mails with the actual message not downloaded from the server. It would be great if an app. existed that could remove all these messages.
Thanks
olav

The most comprehensive way to approach this, is as follows:
1) Make another New Mailbox, and this time Move all the OTHER messages (those you wish to save, anyway) to this New Mailbox.
2) Delete the first new mailbox you created, if Mail allows -- if not we will deal with this later
3) Quit Mail, and in the Finder open Home/Library/Mail/this POP account folder, and find the INBOX.mbox folder. Open this folder, and then within it, open the Messages folder. Delete those xxxx.emlx files for the messages you allowed to remain in the Inbox.
4a) Again in the Mail folder, find the file named Envelope Index, and delete it -- do this to any other file with Envelope in the name.
4b) If Mail did not allow the deletion of the first new mailbox, find and open the Mailboxes folder (within the Mail folder), find that xxxx.mbox folder and delete it.
5) Relaunch Mail, which will announce it is ready to Import your mailboxes -- allow this to continue, and it will not be importing anything, but rather reindexing all your mailboxes.
If you will do, first check the topic where I worked with another on a similar issue at:
http://discussions.apple.com/message.jspa?messageID=2835057#2835057
If you open the stubborn message, and click on View in the menubar, place the cursor on Message and choose Raw Source, you can observe all the header characteristics and report. But if you had rather not bother, don't worry about it.
Keep us posted.
