Thousands of duplicate messages in Apple Mail

On MacBook Pro: OS 10.6.8, Mail v. 4.6, using gmail as a POP (not IMAP) account:
Messages are being duplicated by the thousands in Inbox, Sent, and Trash. This is happening on two MacBook Pros using a single email address. The more we delete the messages, the more appear! We're seeing 1700+ being downloaded as we are deleting from these mailboxes. It's as though we've set up a closed loop between these mailboxes, and the messages are being multiplied exponentially! The downloading stops if we go off-line, but our gmail server Inbox, Sent and Trash don't show unusual activity. When the messages are being downloaded by the hundreds, they are downloading much faster than our internet provider (Telus) can download, so for that reason I believe this is internal to Apple Mail. But how does that fit with the observation that the bizarre activity stops when we go offline?
The gmail account was activated only 2 weeks or so ago, and the problem has occurred only after then, and only with messages on gmail. I had been sending a copy of all outgoing messages to our address by adding a BCC: <our gmail address> so that my wife knows the content of the outgoing messages on her computer. Has this set up the loop?

How do I find duplicate messages in Apple Mail?

Hi,
How do I find (and delete) duplicate messages in Apple Mail ?
I will have to verify about 1000 messages in different mailboxes, all in Apple Mail.
My system: Mail 4.5 (1084) and Leopard 10.6.8.
Many thanks,
D.M.

in any window on a mac, if you just type a letter on the keyboard, the selection in that window will go to a file beginning with that name. In Eudora, if mail window was sorted by NAME and you typed "E" the selection would move to the last email received from a person who's NAME began with "E", if you typed "El" it would move to the most recent email received from a person named "El" if you typed "Ela" the selection would move to the most recent email received from a person named "Ela". If mail was sorted by SUBJECT, it would move to the SUBJECT with those same beginning letters. In mac mail the selection doesn't pick the most recent email, but a completely random one, and it doesn't differentiate between subjects and senders. If I type "josh" it goes to an email with subject: josh, from 2011, not the most recent email from my friend josh that I got yesterday, even though I have my mail sorted by name. If I type "Karen", selection moves to an email received from Karen in 2010, not the one I received 2 weeks ago. In other words, it's completely random and useless.
only way to find something in macmail is to type a name into search box, then organize by name, then scroll to that name, only sometimes those name emails are not sorted by date, so you have to look through to find the most recent one. then once you found it, you need to delete what's in the search box, and reset the sortation to be by date in order to have a chronological listing of you emails. In other words, many complicated steps instead of one simple one.

View Duplicate Messages in Apple Mail 7.3 in Mavericks

Hello,
Up till at least OS X Lion, if there were duplicate email messages, there would be a blue link in the header of the message in Apple Mail that you could click on to reveal the duplicate messages.
Im currently running Mavericks and Apple Mail 7.3.
By default, there no longer seems to be any indication that there are duplicate messages?? Is that correct???
I have found the Terminal commands that will allow me to "ungroup" duplicate messages:
To disable automatic grouping of duplicate messages, quit Mail then run this command in Terminal:
          defaults write com.apple.mail AlwaysShowDuplicates -bool true
To revert to the default setting, run this command:
     defaults write com.apple.mail AlwaysShowDuplicates -bool false
or simply delete the setting altogether with this command:
          defaults delete com.apple.mail AlwaysShowDuplicates
If you want to see how Mail behaves with this setting enabled, but without modifying your preference file, start Mail from Terminal with this command:
          /Applications/Mail.app/Contents/MacOS/Mail -AlwaysShowDuplicates YES
These seem to work fine as far as listing the duplicate messages in the message list.
HOWEVER . . .
What I am wondering is . .
Is there no way to leave the duplicates "grouped" so there is only single entry in the message list BUT have the link in the header that indicates that there are duplicates and allow you to click on that link to reveal the duplicates in the message list???    I find having the link in the header easier to work with rather than having ALL of the duplicates ungrouped in the message list.
ALSO - for what it's worth:
I also tried setting the "Show Header Detail" option in Mail Preferences to "Custom" which includes an entry called "Duplicates" in the list of times displayed in the custom header but I still do not get any indication (that I can see) that there are duplicate messages . . .
Any ideas or experience with this????
John

How to remove thousands of duplicate emails in Apple Mail?

Hi everybody,
I know there are a couple of discussions on the web already about this issue, but I cannot find one that clearly answers my question or solves my problem.
I'm working on Lion with Mail version 5.1 and I have a Gmail-account. I have been messing around a bit with IMAP and POP to re-collect all my Gmail-mails into Apple Mail, but now I see that almost every email has 1 to 5 or even more duplicates.
I've tried Andreas Amann's "Remove Duplicates" script, but whatever Mailbox I check, it doesn't work with Lion (yet). I get this error:
There is another script I tried, the one from this page: http://hints.macworld.com/comment.php?mode=view&cid=115625
It just makes my computer freak out, so not OK.
A third script I found here: http://jollyroger.kicks-***.org/software/
I downloaded the "RemoveDuplicateMessages-Mail.zip"-file and installed it. It does say it finds and relocates duplicate mails from the Mailbox that is selected in Mail:
It relocates all the duplicates to a folder on my Desktop, called "Remove Duplicate Messages". I do find them there, but the mails in the selected Mailbox in Mail.app still show their duplicates! Even when I throw the files from the new folder on Desktop in the Trash and empty it, nothing changes. Not even after restarting Mail. Or my Mac.
So I'm still stuck with thousands of duplicates. Any help on this one?
Thanks a lot,
Alexander

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.

How can I always display duplicate email messages in Apple Mail?

I would like to have Apple Mail ALWAYS display "duplicate" messages without having to click on the duplicates link in the upper right of the message.
Apple Mail identified a series of messages as "duplicates" when in fact they were not duplicates. I would have otherwise missed out on very important information and the only reason I even knew to look for this was because I saw them on my iPhone. I want to avoid this issue in the future.

Comfortable with terminal...know how to edit using TextEdit:
Open up a Terminal and use the following commands to change your Mail.app preferences file to an XML format – the default format is binary, and you can't edit this.
cd ~/Library/Preferences
plutil -convert xml1 com.apple.mail.plist
Then, open this file com.apple.mail.plist with a text editor of your choice, preferably one that highlights XML syntax, but you can also use TextEdit:
open -a "TextEdit" com.apple.mail.plist
Now, look for the key called MailAccounts. It's value is an array, with dict children. Here, you'll find all your mail accounts in the order they were created in.
You can now manually move these dict children around. Save the XML file and reopen Mail. Now, your Mail account order will be changed.

How to ENABLE detection of duplicate messages in Mavericks Mail?

Hello,
There was a good discussion of how to disable detection of duplicate messages in Lion mail - https://discussions.apple.com/message/18265121#18265121
but unfortunately nothing seems to work to turn them ON in Mavericks.
In Lion or Mt. Lion I do see duplicate messages - but in Mavericks I do not - but I want to see if there are duplicates for a variety of reasons.
In the post referenced above none of the command line suggestions seem to make a difference. My mail perference settings are idential on each system, be it Lion, Mr. Lion or Mavericks. Settings as follows:
Please note 'include related messages' seems to make no difference either way.
Can anyone please tell me how to display duplicates in Mavericks. Thank you very much in advance.
E.

As a quick update, the following command DOES in fact show the duplicates in the mail folder:
defaults write com.apple.mail AlwaysShowDuplicates -bool true
So, if there are two exact messages (one sent to me at [email protected] and one forwarded to that email address and sent to me at [email protected], BOTH will show up as separate messages.
But to be clear, what I want to see is a single message with the '1 Duplicate' indicated in the message header.
Any way to do that in Mavericks?
Again, thanks in advance.

TS3276 How to remove duplicate emails in Apple Mail program

Removing corrupt messages in Apple Mail

I have 6 identical messages in Apple Mail dating from 2006. I cannot delete them or move them. I've been told it is due to the messages being corrupted. OK. How do I get rid of them?

Not certain, but this can fix myriad Mail problems...
Safe Boot from the HD, (holding Shift key down at bootup), it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move this folder & file to the Desktop.
Move this Folder to the Desktop...
/Users/YourUserName/Library/Caches/Mail/
Move this file to the Desktop...
/Users/YourUserName/Library/Mail/Envelope Index
Reboot.
If that doesn't do it and you can afford to redo all your Rules, try these & reboot...
/Users/YourUserName/Library/Mail/MessageRules.plist
/Users/YourUserName/Library/Mail/MessageRules.plist.backup
Note, in 10.5 & up /Users/YourUserName/Library/Caches/Mail/ may or may not exist.

Empty messages in apple mail

One of the email lists that I subscribe to frequently contains messages with images. It's a moderately high volume list with 20-30 messages per day. Inevitably, a few of those messages with attached images (according to the paperclip icon in the messages list) will arrive with no headers and no raw data. The display of the message in Apple Mail shows only the sender's name/address and the subject, nothing else such as the usual warning, "This message contains no content."
The people who run the mailing list don't think that the problem is on their end so I am here asking whether this is happening to anyone else and, if so, is there a way to correct it.

Thanks to Linc Davis and dot.com for the replies.
Here is some add'l info that may or may not shed light on this issue.
I tried to follow Lin's suggestion to see if the message was intact in web view. Unfortunately, I was unable to find it. This is an Office 365 account. Apparently, messages are deleted as they are sent to my MaxOS X 10.10.1 account. I could only find two messages for today when Apple Maile shows more than a100 incoming. Thus, I was unable to cross check in this way.
However, I was able to replace this issue o/s of the mailing list server and Office 365. What I did was log into my iCloud web account and use Pages to send an email with an ePub attachment. I sent his twice, once to my @me.com address and one to my Office 365 account. The one sent to my iCloud account arrived intact. The one sent to my Office 365 account was empty – no attachment whatever. So this issue has to do with attachments as handled by Office 365.
Unlike the previous cases, I was able to see both the Headers and Raw versions of the email.
I see no clues in these data sets but include them here in case I have missed something. Here goes:

As recommended by several tech sites, I enabled All Mail from my Gmail account to show in IMAP, and Apple Mail 8.0 created a new archive under the Trash icon named "All Mail (Google)". It took several hours to downloaded all my 63000 messages and they are now all stored there (based on the mailbox size in Library>Mail) but still show (as aliases I guess) in the respective mailboxes that I originally assigned them to.
Now, when I search for a message in Apple Mail, it finds it but shows its location as in "All Mail" instead of the mailbox (or label) that I had assigned it to. Is there a way to hide the All Mail archive so that the search function does not look there first?
I used to have All Mail disabled in IMAP, and the search worked as I wanted, but the issue was that all my 100 mailboxes had to be synchronized every time a message arrived, was deleted, or was moved from any Gmail mailbox. This means that it constantly cycled in the background through my mailboxes and new mail sound notifications were delayed until all mailboxes had been synced.
Enabling All Mail to show in IMAP has solved the issue of constant syncing to all mailboxes, but it has introduced the problem with searching my mailbox. It has also meant that every new message that arrives is displayed both in the Inbox and in the All Mail, and I don't need the latter.
I opened a ticket a year ago about the syncing issues to all mailboxes with bugreport at Apple, and nothing has been solved. Thanks for any help on how to hide the All Mail Google archive without disabling All Mail in IMAP, or any other workaround to search messages by mailbox without having syncing issues.

Still having this issue and accidentally hit solved.

IPad Mail messages from Apple mail

New ipad getting 10,000 old messages from Apple Mail application (or Comcast server). How do I stop it and get only new messages as of today?

These are emails stored in the Sent folder in Mail, in 2 email accounts. Some are quite old, some recent. In addition, the Mail Inboxes were emptied, leaving only those emails that had been unopened. Those still on the server (I looked at Get Account Info in mail on different Mac to identify which) were downloaded and are in place in the ipad . In short, those lost were emails received and sent, stored locally on the ipad.
When I did the update, it said there was an error so I had to backup and restore, via itunes. I thought emails would be backed up in this proces. I don't use icloud. Thanks

How to disable detection of duplicate messages in Lion Mail?

When Mail in Lion detects duplicate messages in a mailbox, it groups them together and shows the link in the header "x Duplicates", where x is the number of duplicate messages found. When that link is clicked the duplicate messages show in the mailbox separately. But I'd like Mail to stop grouping them together to begin with.
Running OS X 10.7.3 and Mail 5.1

To disable automatic grouping of duplicate messages, quit Mail then run this command in Terminal:
     defaults write com.apple.mail AlwaysShowDuplicates -bool true
To revert to the default setting, run this command:
     defaults write com.apple.mail AlwaysShowDuplicates -bool false
or simply delete the setting altogether with this command:
     defaults delete com.apple.mail AlwaysShowDuplicates
If you want to see how Mail behaves with this setting enabled, but without modifying your preference file, start Mail from Terminal with this command:
     /Applications/Mail.app/Contents/MacOS/Mail -AlwaysShowDuplicates YES
I learned of Mail's modifiability (is that a word?) from here:
     http://hints.macworld.com/article.php?story=2004101603285984
and here:
     http://erikslab.com/2007/07/16/os-x-mailapp-logging/
I found the AlwaysShowDuplicates option by looking for interesting words similar to 'duplicates' in the Mail executable like this:
          strings /Applications/Mail.app/Contents/MacOS/Mail | grep -i duplicat
