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

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.

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.

How to disable buffering of similar messages in syslog?

Hi All,
Following is my system details:
SunOS mocm 5.10 Generic_138888-03 sun4v sparc SUNW,Sun-Fire-T200
On this system I see that, similar messages passed to syslog are suppressed after the first entry and only the count of the number of times that message got repeated is printed. However I want all the logs to be printed even if they have same content.
Here is what I am getting now:
+Jul 13 12:01:54 mocm Application[26103]: [ID 441523 local1.notice] xxWriting from stub+
Jul 13 12:01:54 mocm last message repeated 1 time
+Jul 13 12:02:45 mocm Application[2845]: [ID 188083 local1.notice] Writing from stub+
Jul 13 12:02:45 mocm last message repeated 2 times
+Jul 13 12:02:56 mocm Application[4485]: [ID 441523 local1.notice] xxWriting from stub+
Jul 13 12:02:56 mocm last message repeated 7 times
and this is what I want:
+Jul 13 12:01:54 mocm Application[26103]: [ID 441523 local1.notice] xxWriting from stub+
+Jul 13 12:01:54 mocm Application[26103]: [ID 441523 local1.notice] xxWriting from stub+
+Jul 13 12:02:45 mocm Application[2845]: [ID 188083 local1.notice] Writing from stub+
+Jul 13 12:02:45 mocm Application[2845]: [ID 188083 local1.notice] Writing from stub+
+Jul 13 12:02:45 mocm Application[2845]: [ID 188083 local1.notice] Writing from stub+
Is there a way I can configure syslogd to print all the log messages instead of buffering similar messages.
Thanks in advance for replies.

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:

or simply delete the setting altogether with this command:

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????

but in MacMail they are all there still.
i found that in macmail settings "remove copy from server after retrieving a message" was selected(after one week). (now i have disabled this function)
how can i send them back to the hotmail server email box?
Many thanks in advance for help. Rick

I do not know if you can unfortunately, having deleted them from the POP server and as Hotmail does not offer an iMap or Exchange solution for OSX they may be 'marooned'
I will search around and see if I can find a solution.
But before anything else happens backup your mail (Mailbox Menu>Export Mailbox) and save the file somewhere you can find it, you probably don't need to hear this but you should be (have been) backing up regularly, for this and many other reasons.
I'll post back if I can find a solution to the issue.

Duplicate messages in sender mail adapter

Hi,
We are using the sender mail adapter to retrieve messages from an IMAP mail server. Messages are being picked up correctly, but when we have large messages (with e.g. PDF attachments) things go wrong.
The time it takes to retrieve the mail message is longer than the poll time. In this case the adapter logs in again in the mail server to retrieve the first new message from the inbox. However the first adapter threat is already retrieving that message. This results in a duplicate message in XI. (messages are set to be deleted when read).
We have tried all kind of settings in the adapter but without any results. The adapter works fine with very small messages.
Does anyone recognize this problem?
PS. please do not post links to sap help or the mail adapter FAQ. Useful answers will be rewarded.
Thanks,
Christiaan Schaake

Hi Christiaan !
I understand your problem. Could you set your IMAP account to avoid multiple simultaneous sessions?? maybe if there is only one session allowed per user or per time, then parallel XI threads will not be able to start downloading the messages.
If you cannot use a longer poll interval, then you could develop an adapter module for the Mail sender adapter that could be used to verify if the current mail is just being downloaded by other thread. This adapter module could check the unique mail data (date/time + subject + etc.) against a local table.
Regards,
Matias.
PD: please award points if helpful.

How to not "read" Junk Messages In Lion Mail?

In the new setup in Lion Mail, the left column now has the subject line and first couple lines of the message.
To create any kind of action with the message, I have to select it. It then appears on the right and is seen as opened mail.
For most messages, this is okay, but for junk mailing (foreign entitities wanting money etc.), I don't want to open it but I do want to delete it.
Does anyone know how I can delete without "selecting" the message and automatically opening it or do I just have to use the alternate older view of Mail that is provided?

I second this... Some emails I don't want to see at all. (i.e. Prince SoNSo has left me a gazillion dollars, all I have to do is reply...) Is there and edit button in the new mail as similar to the one used on portables?

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 to disable [drm] and ntpd messages on console ?

http://s9.postimage.org/e3ymmtxlr/tty1.png
As you can see in the picture above, i want these messages not to apear on my console.
I even can not write my user name to login because of them. ANNOYİGGGGGGG.
I have to pres ENTER and sometimes lots of buttons to find a "Tombik(my hostname) login : ___" inscription.
Also, the message below appears after the udev in the initscrips at the begining of the system.
dd-nn-yyyy hh:mm:ss [drm] nouveau xxxx 1:00.0: no native mode, forcing panel scaling
My /etc/rc.local file includes,
{ ntpd -qg; hwclock -w; } &
( I added this code as mentioned "Synchronize once per boot" section on here , for synchronizing my system date.)
How can i prevent "[drm] nouveau.....forcing panel scaling" and "ntpd" messages not to be shown in the beginning system messages and my main console ?
( i use "drm_kms_helper.poll=0" and "quiet" in my /boot/grub/menu.lst . But they only solve screen flashing and "[drm] nouveau.....forcing panel scaling" message in every 10 second .)

How to disable Unicode in SMS messages (Nokia 6670...

Hello.
I've bought N6670 and the first thing I want to change, is to disable Unicode charset in SMS messages. I use T9 dictionary, so the Unicode special charset is enabled (I'm from Poland, so there is a lot of special chars).
But - of course - message with special chars is bigger, so the phone sends for example 2 messages, instead of one.
Is it any chance to turn of sending special chars?
Regards
R.

Hello,
We use such messages in transliterate characters. As example, privet.
That's the easiest way.

How to Disable Popup Preview of Messages?

Hi. I'm just trying to figure out if there's a way to stop Mail.app from popping up the small preview of messages in the top right corner of the screen when they're first received. I find this incredibly annoying. I've searched thoroughly for a solution to this, but all I can find is how to remove the preview pane, which is not what I need to do. I don't know anything else to call this feature besides a "preview," which makes it hard to search for a solution, since so many of the results center around the preview pane. I would greatly appreciate any help you can offer. Thanks.

Thanks. I appreciate it. I don't know why this doesn't annoy more people. When I'm working, I get tons of emails around the same time. The last thing I want is to constantly be visually interrupted when the new mail sound suffices. Either way, thanks for the help.

How to disable Disk Insertion warning message?

I'm running OS X 10.4.8 from an external FW drive, reserving the internal HD on my MacBook for Linux. When booting OS X a warning message pops up: "Disk Insertion - The disk you inserted was not readable by this computer" with action buttons Initialize..., Ignore, Eject . This must refer to the internal HD, as OS X apparently can't handle Linux partitions. Hitting Ignore, or waiting a while, makes the message go away.
My fear is that one of these days I'll hit the Initialize... button by mistake, hosing my Linux partitions in the process. Any gurus out there know how to turn this dangerous (for me) message off?
N.B. I also posted this message on the MacBook forum, but got no response there... sorry for this, I really want to remove this potential landmine...
MacBook Mac OS X (10.4.8)

No. If you fail to eject any disk device properly then there's a risk that cached data will not be fully written thus corrupting the device's data.
This doesn't happen with an iPad or iPod when syncing has stopped because the sync process does not leave cached data unwritten until the device is ejected unless you remove it before a sync has completed. It will happen, however, if you use the iPod in disk mode. The iPad has no default disk mode. You must use a third-party app in order to read or write directly from an iPad. The issue is also academic for iPads and some iPods that do not have disk drives.

How to disable Install/Upgrade popup message?

I just logged into my computer this morning and a popup message tells me to install Java 1.7. Of course I can cancel, but since I have 200 user PC and users should not be using Java 1.7 yet I would like to know can this popup message be disabled?
Thank you in advance.

I don't think there's much you can do about that apart from maybe disabling all pop-ups in Settings-Safari

How to disable the windows update message "Windows update hasn't been able to check for updates for the last 30 days"

Hi,
We work on a domain that uses Symantec Management console to administrate our patch enviroment. We have windows updates disabled. But our Windows 8 machines get this message once a month
"Windows update hasn't been able to check for updates for the last 30 days"
Just wondering if anyone knows which GPO to use to disable this setting as I have been unable to find it.
Thanks

Hi，
You can turn off the message by GUI in Control Panel\System and Security\Action Center, in the right pane, click "Change Action Center settings", then untick the "Windows Update" option.
For GPO, you can disable all balloon notifications:
User Configuration \ Administrative Templates \ Start Menu and Taskbar\Turn off all balloon notifications
Or remove Action Center icon itself
User Configuration\Administrative Templates\Start Menu and Taskbar\Remove the Action Center icon
And I haven't found a GPO to turn on\off a specific message mentioned in the action center, but the setting for the message is related with registry key under
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Action Center\Checks
but the value under the key is binary, hard to control, if you have interest, you can export the key from a preference pc, then deploy the GPO via
User Configuration > Preferences > Windows Settings > Registry
