Multiple Copies of Emails

finder -> applications -> mail -> CMD+i -> open in 32-bit mode

Thanks! We'll see what happens.....

I've been experiencing this issue as well. I too have gone through all the suggested fixes in this thread and also confirm that the issue is not solved.

I've seen some messages in Console that seem related to this issue, and wonder if anyone else can confirm this. These messages are coming from Mail:

Seen Messages: error "%{PROPERTY}@ is a required value." in -[SeenMessagesManager saveChanges]

If confirmed, this leads to further finger pointing at Apple.

Well, once again, out of the blue ... all of my e-mails from the past week, just downloaded – AGAIN. I wasn't even at my computer and no processes were running. This is the most random occurrence yet. Can't wait for that 10.6.2 bug fix Apple!

Well, despite having been quite harsh on Apple over their lack of responsiveness I have to admit that there is something very strange going on here.

I forsook the Mail.app a couple of weeks ago for Postbox on my Mac and I have been very happy with that. I have had zero duplicate emails on my Mac since doing that.

On Friday this week however, on a single POP account on my iPhone the following happened.

1) Both the Mac and the iPhone at different times reported being unable to contact that particular POP server, however, that was only for a few minutes each;
2) The Mac subsequently picked up mail from that account - 1 message;
3) The iPhone accessed that account and downloaded duplicates from the account for the last 10 days.

That's the first and only time I have ever had duplicates on my iPhone.

I have no idea what is going on but clearly there is an email anomaly that is more complex than first thought. I feel like I only have access to part of the jigsaw.

However the common denominator is that I have only ever had duplicates using an Apple Mail application - whether on the Mac or the iPhone.

I am running now a packet analyzer, in the hope to grab the commands sent to the server in the event of duplicated mail downloads from pop3 plain. I might be lucky in finding something but I suspect there's a better way to log all Mail server commands activity; however I want to ask the people that are experiencing this issue: how often did you set up Mail to check for new mail?

Maybe unrelated but mine is set to check every minute.

I have seen the iPhone download duplicates in the past but it has only ever been a single message, even when there are several on the server. I have always put this down to an interrupted session.

maybe it's already been reported but I got the console logs when mail is duplicating messages.

seems there are two messages sent to a class object in Mail.app:

-[SeenMessagesManager _accountForAccountID]
-[SeenMessagesManager saveChanges]

both are raising an exception about the fact that they cannot open, for some reason, MessageUidsAlreadyDownloaded3 file, despite the fact that the file is in place and have permissions.

it's a bug in Mail.app; the exception raised is localized (Italian in this case).
Mail tries hard to find this file, at least 10 times per second, for 4 seconds before probably giving up and redownload all the stuff.

My best guess is that this file become locked during certain processes and not accessible, but the error raised is pretty generic, it just says that cannot open the file, not why.

The replication issue hit me the past two days. The number of duplicate emails increases every time email is checked, regardless of whether it is read and deleted or not. I am using Verizon FIOS and Mail 3.6. I have tried deleting and adding the account in Mail, with no effect.

The problem for me seems limited to email from Gmail accounts going through the mac Mail software. I have checked my inbox online and there are no duplicates.

Just got 4 copies each of nearly 500 messages, now I get to pick through and delete the dupes (AGAIN.) This has been happening daily, sometimes multiple times. It's making Windows look inviting. Why no response from Apple?

I just want to say that I have not had this problem since I set Mail to run in 32-bit mode. We'll see if that lasts, but so far, 3 days with no problems in 32-bit.

Anyone here had the problem in 32-bit?

Yup. I can only run 32-bit. Been plaguing me since day 1. But keep guessing ... seems to be what Apple is doing.

Now just two days later, I got another duplicate dump. Absolutely no rhyme or reason. This after several weeks of at a least a week or more between dumps.

Again, nothing unusual happening on my MacBook.

Well I spoke too soon. This afternoon it was mere 60 or so e-mails (looks like it was just one account). Tonight, I just had 564 e-mails download out of the blue, including the ones that came earlier today! So now it seems to be happing twice a day. Again I'm doing absolutely nothing differently than any other day when this happens.

Hi, Masterkain
I have had a number of conversations with Apple Euro regarding this. They continue to try to blame email providers.
I have sent your findings to the tech that I am dealing with. Any further stuff that you have might help.

Well do they include MobileMe in the ISPs they blame? That's the only account I've got set up with Mail.
