Duplicate POP Mail

I am receiving duplicate copies of my POP mail...I set leave mail on POP server for a month, because I don't want mails deleted too soon, I am not always at my copy and would like to view my POP mail via the web. It seems the only way to not get the duplicate mails is to set delete from server when mail is downloaded. If this is the case this is really bad...With Microsoft Office Outlook, I can set Outlook to receive my POP mail without receiving duplicates when the mail is left on the server
  Mac OS X (10.4.8)  

You should be able to leave mail on the server for one month without getting duplicates, but Mail appears to have this kind of problems with some POP servers. Whether the culprit is Mail or the server, I don’t know. I’ve seen cases reported here (some Yahoo accounts a few months ago) where the culprit was clearly the server. You may try clearing things up and start over by clicking the Remove now button in Preferences > Accounts > Advanced. I would also try changing the setting to After one week and see whether that makes a difference.
Another thing to try would be deleting the file that Mail uses to keep track of which messages have already been downloaded, in case there is something wrong with it. Problem is, deleting that file will cause Mail to treat all the messages still on the server as if new and download them again. Hence, you may want to remove messages from the server before trying the following procedure:
1. Quit Mail.
2. In the Finder, go to ~/Library/Mail/POP-username@mailserver/.
3. Locate one or two files named MessageUidsAlreadyDownloaded and move them to the Trash. Mail 1.x used MessageUidsAlreadyDownloaded to keep track of which messages had already been downloaded. Mail 2.x uses MessageUidsAlreadyDownloaded2 for the same purpose.
Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder, i.e. ~/Library is the Library folder within the user’s home folder.

  • How to remove duplicate POP messages in Mail under Mavericks

    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 (even the trash) so that I have a permanent record of all conversations, going back more than 10 years - this is about 250,000 emails in around 250 subfolders. 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. I left 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 planned 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. I also rebuilt all the folders again, which doesn't seem to have resulted in any further loss of messages as far as I can tell. 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, because of the 'hidden' messages), a slow and unresponsive Mail program. I've come to the conclusion that there must be some corrupted email somewhere, which probably caused the original email haemorrhage, and may still be causing the inability to remove duplicates. Mail is so slow as to be almost unuseable.
    I figure I have a number of options:
    1. I could live with the situation and just archive most of the Mail in my inbox, with the side effect that there will be a bunch of messages I have never replied to that are missed.
    2. I could abandon the last week's efforts and revert to the version of Mail I was using a week ago, and then redownload the recent emails from my various accounts. That would still leave me without those thousands of emails I lost on my local machine.
    3. I could find another way to deal with this. Can I get the remove duplicates script working? Should I revert to the version of Mail from a week ago, download ALL the messages again, but do it in a way that allows me to find the duplicates and remove them? Should I move to another email program altogether (which would presumably be massively disruptive to my work!)
    Anyway, apologies for the essay length of this request, and thanks in advance for any help you may be able to offer!

    hi Eric
    thanks for the tip, but I don't think that solves my problem, which is that Mail apparently hides the duplicates, so they're still there, you just can't differentiate or remove them. I actually *need* the duplicates there so I know I've got everything, but then I need to be able to move the ones I know I've dealt with from my inbox to an archive/trash, and/or remove them completely so Mail isn't totally bloated

  • Pop mail account and duplicates on mail.ap

    Hi,
    Mail is duplicating messages, I have a pop mail account and the preference setting is to erase messages on the server.
    Some duplicates are from Nov 2006; after I erased all messages using the terminal and ssh connection.
    I was told to rebuild mail index and did it, no improvement.
    .......... any help appreciated, I have invested many hours into erasing duplicates ... thanks, Garrett
    Why don't you try rebuilding your Mail index:
    1. Quit Mail if it's running.
    2. Go to ~/Library/Mail and delete the Envelope Index file.
    3. Restart Mail and wait for it to import your existing messages. When that's done, any duplicates or ghost messages should be gone..

    Sorry, both at once is confusing in retrospect.
    Just meant backup the whole works and drag the current cache & envelope out of their locations to the desktop.
    What about the plist?
    You can make a Copy of that to move to the Desktop. Sometimes that needs to be made anew also, but requires putting in account info and such, so we generally wait on that one.
    What about the files on the desk top?
    If everything works right, we can trash them, if nit we can mive them back.
    I'm not sure from these ideas what might be the result or why there is a problem in the first place.
    Same here, but those files can become corrupt.

  • Mail 2.1 re-downloads already downloaded POP mail!

    I recently installed Mac OS 10.4.9 on a new Mac Pro tower and my older 15" G4 Powerbook. The OS comes with Apple Mail 2.1. The problem I'm having is with Mail 2.1 regarding retrieving POP mail from the Yahoo server that has already been downloaded. Since I don't routinely clear messages from the Yahoo server, repeating a download from scratch can mean over 9000 messages. This results in duplicate messages piling up in my INBOX.
    Since I download POP mail to both of my computers, I don't want to clear the Yahoo server of mail.
    How do I prevent Mail 2.1 from downloading already downloaded POP mail without clearing the server?
    Powerbook G4   Mac OS X (10.4.9)  

    The first time to download the messages was 2 weeks ago when I reformatted my G4 Powerbook with the new Mac OS 10.4.9. I then set up the Apple Mail 2.1 to retrieve messages from the Yahoo server. It downloaded all the messages just fine.
    Then about 1 week later, when routinely checking for new mail, it started downloaded from the Yahoo server just as it had the first time (thereby creating dulicate copies of every mail message).
    This has forced me to clear the Yahoo server, which I really didn't want to do.
    This problem is not severe, I understand. But the older version of Mail never had this problem over 2+ years of use.

  • Duplicate e-Mail Since Upgraded to 3.0

    I am receiving duplicate e-mails on my iPhone since the upgrade to 3.0 when retrieving over the air or from wi-fi. I have an original iPhone (2G) with 16g. I have 3 e-mail accounts, 2 are from gmail (both giving me duplicates) and 1 from ATT (no duplicates). The e-mail service with gmail on my MacBook are using IMAP, whereas the ATT mail is POP. e-Mail on my MacBook is just fine, as it is if I retrieve via the net from gmail. Only duplicates appear on my iPhone.
    If I delete just one of the e-mails, it actually deletes both. So I have to choose to keep both, or both get deleted.
    Any solutions out there to this, or is Apple addressing??
    Thanks

    I'm having the same issue with a POP account on my iPhone 3G S with OS 3.0 (I didn't have this before with the same account config on a 2.x 3G, which I upgraded.) My GMail and Yahoo! mail accounts seem to be OK (although I don't get as much mail at either of those).
    The duplicate issue comes and goes; not every message is duplicated on my iPhone. None of the messages are actually duplicated on the POP server.

  • My firefox recently updated. Now my pop mail server won't work. I did a 'restore' to last week, and it was fine. It has now auto updated. No mail server.

    I have read through several responses to others who are having problems following an update. I am not computer savvy enough to understand half of the recommended 'solutions'. I need clear and definitive instructions of what to do. (Instruction for 'dummies' is what I need.) I can not 'restore' my computer continuously, only to have the auto updates cause the pop mail server to stop working each time. If there is nothing I can do, I guess I will have to stop using Mozilla Firefox. Can you help?

    There is no solution for Firefox and POP. Firefox doesn't do email and has no need for a POP email server.
    If you are using Firefox to view and send "email", you are accessing a webmail service provider.

    Hi Rob
    It sounds like my problem is the same as yours..... Sorry, but I'm a bit of an iPad dummy so am writing for some more clarification...
    My problem is..... I am away from home and only travelling with my iPad, however we have sold our house and my bigpond email address on my iPad is getting clogged with all the solicitors stuff etc, so I really need these emails for my files...
    I want to be able to backup these up (so that I can retrieve them later to print out and file) and delete them from my iPad...
    I've just created an iCloud email account (I think) is this what you did? So should I forward all my emails to this iCloud email account? And will I be able to retrieve them later?
    I hope you login here to see my question.....
    Thanks Janet

  • Is there any way to sync POP mail between iOS and Mac devices via the cloud?

    The title says it all.  I have Comcast email and would like to keep three devices in sync with email like I do with calendars and contacts.  I use an iPad, iPhone, and a Mac Mini and am having a hard time configuring the three to stay in sync.  It seems that a .me account is needed for cloud email, which I have, but that only seems to send via the .me outgoing server.  So, while a .me account can retrieve the POP mail, it doesn't send outgoing mail correctly for me.  Maybe it just isn't possible.

    When I send mail from my mobile devices, it comes from my .me account.  Same for my mac.  But, I don't care because no matter which email the recipient responds to, I get the response.
    I use my .me account now as my primary account, but I have a ton of folks who still use my cox account as my primary email address.  Most don't even know which account the email is being directed to.

  • How to preserve messages on ISP after setting up mac POP mail?

    I recently (YESTERDAY) set up POP mail (mail 3.3) on my new macbook to collect mail from my yahoo account. AFTER downloading my yahoo inbox I noticed that one of the default advanced settings in mac mail was set to ''remove copy from server > after one week' from the ISP (yahoo).
    As I certainly do not want this to happen I unchecked that option so that mac mail will not delete any messages it collects using POP and the contents of my yahoo inbox will remain unchanged.
    But I'm worried that, even though I've unchecked the instruction to delete messages from server in 1 week, that somehow the instruction to delete will still be 'in the system' and that the contents of my yahoo inbox that my mac mail has already collected will somehow be 'tagged' for deletion in a week. Note that currently all my yahoo inbox messages are still in my yahoo inbox, but will they be safe in a week? Should I do something to safeguard against this like move those message out of my yahoo inbox and into a separate folder? Or ??
    Any advice appreciated

    The default behavior for accessing mail via POP is to transfer the messages to the client and delete them from the server, but some clients can disable the erasure. However, after doing this, some clients are unable to retrieve the unerased (but read) messages for the second time. I haven't tried with Mail to see if this works with Yahoo; I know for a fact that it doesn't with our corporate mail server.
    Is there a possibility to use IMAP instead of POP? (Which is what I believe .Mac mail uses)

  • Can icloud email receive email messages from another account by automatically retrieving them like my iphone does. Microsoft calls this pop mail

    I have an iphone and an ipad. I don't have an Exchange email account pulling all my messages from my verizon email account into my apple devices. My husband uses his Outlook computer at work to create 2 Inboxes on his iphone (one is his work email Inbox and one Inbox is his pulling from his personal account). I noticed using an Exchange-type email program with the iphone allows for features I want. I want to check email on my phone and ipad. I ALSO want to be able to file emailed coupons into an Inbox coupon folder on my phone and ipad for easy retrieval. It seems the icloud email program will let you do all of this. It also seems Google offers gmail and it will do this for me. Now that I set up an icloud email address, I can't figure out how to get Verizon email pulled into it. My iphone and ipad pulls my Verizon email but does not allow for Inbox folders. Verizon won't auto-forward emails to another account. Gmail will pull them for me though. Will icloud do this?

    Verizon netmail just offered auto email Forwarding. So, even though icloud might might not offer the services Gmail and other email programs offer to pull email, it seems I might still be able to accomplish what I want using the other email account's ability to forward my email to my icloud email address. We'll see. Please reply if you know the answer to the icloud's ability to pull email in a way like pop-mail does for pc users. It would have helped me if I could've found the answer to that question in this support forum...

  • Can I set up a Non .mac Email Pop mail client Alias for sending SMTP mail?

    I have a yahoo.com POP mail account - [email protected] When I'm lgged into Yahoo mail, this account can receive and send mail from serveral aliases - [email protected], [email protected], etc.
    Using Tiger's mail.app, I can log into the Yahoo smtp server and get all my mail, including mail to the alias names.
    I would like to be able to reply from my Mac's mail.app account, using one of the aliases, instead of my POP account name. In other words, I'd like the From field be listed as "[email protected]" and not "[email protected]"
    In mail.app (v2.1) is there any way to do this?
    Alan Sampson' suggestion doesn't work - when I set the From field to the alias name, it looks like mail tries to login to the yahoo SMTP server under the alias, and it gets rejected.
    ( - see http://discussions.apple.com/thread.jspa?messageID=2603372&#2603372 )
    Go to Mail > Preferences > Accounts and under the Account Information tab for the primary email account preferences, enter all alias email addresses in the Email Address field for the account separate by a comma.
    [email protected], [email protected], [email protected]
    MacMini - 1.42   Mac OS X (10.4.7)  
    MacMini - 1.42   Mac OS X (10.4.6)  
    MacMini - 1.42   Mac OS X (10.4.7)  

    If Yahoo allows this, it should work. Open Mail Help, type alias in the search box, and read the article titled Adding multiple email alias addresses to an account. Could it be that you're trying to put the aliases in the wrong field (i.e. User Name rather than Email Address)? Or maybe it's Yahoo's SMTP server that doesn't allow you to do this?

  • Using a POP mail account in mac mail

    My friend has an AT&T sbcglobal POP mail account he has added to his mac mail app. Since it is POP mail it is not always received in his mac mail box if AT&T Yahoo account receives it first. I guess he can prevent the Yahoo mail box from downloading the messages if he signs out of the Yahoo account.But he also has an iPhone. So will he still have the race problem between the computer & the iPhone on which gets the mail first?
    Appreciate any suggestions on how this can be solved?

    For POP:
    The following mail server settings will work with all AT&T email domains: @ameritech.net, @att.net, @bellsouth.net, @flash.net, @nvbell.net, @pacbell.net, @prodigy.net, @sbcglobal.net, @snet.net, @swbell.net, @wans.net.
    Email Program Settings Field:
    Enter:
    Incoming (POP)
    inbound.att.net
    Outgoing (SMTP)
    outbound.att.net(requires authentication)
    Incoming mail server:
    POP3
    Incoming/Outgoing User Name:
    Full AT&T email address, including domain (e.g., [email protected], [email protected])
    Incoming mail port #:
    995, secure connection (SSL) checked
    Outgoing mail port #
    465, secure connection (SSL) checked
    I assume the settings you are refering to gives that delay for marking the messages as read when highlighted for that period of time. Probably for scrolling through the list without changing the unread status. Lion doesn't have that selection, so I can't test that at the moment.

    If the Inbox for this account only is revealed, is there any triangle beside it?
    Ah, yes, I see! Silly me to be looking for Sent mail under "Sent"! Indeed, there's a disclosure triangle next to the account name under "Inbox", and wen you open it, it shows Drafts, Sent, spam, and Trash. The sent items are indeed there.
    Mind you, my Dot Mac accounts show up normally, i.e., their sent mail goes under "Sent". Wish all IMAP accounts did that. It sure isn't logical to show sent mail inside an inbox...
    But to answer your question: In addition to having the "Sent" folder for the account under "Inbox", I also have a folder for the account under "Sent". This folder disappears when I check the box to store messages on the server. There were emails in it (the ones I placed there myself). I have now moved those emails to the sent sub-folder under the account under "Inbox". Even with the "store on server" option UNchecked, the emails were instantly duplicated to the server, so that they were present both locally and remotely. I then checked the "store on server box"; this made the mailbox for the account under "Sent" vanish.
    To summarize: things appear to work normally now, except that I find it very inconvenient to have to look in two separate "Sent" folders to find emails I've written.

  • If you delete a POP mail account in Mac Mail can you get your mails back?

    This has happened to a client of mine. She'd just set up a new account for her email as she'd moved servers. She had an old POP mail account on her Mac Mail for two years which she deleted and now all of her old sent mails are gone plus everything from the inbox that wasn't moved into folders.
    How do you get those emails back? (I'm not sure if she has been using Time Machine to back everything up)
    Will re-creating the old account help?

    If she hasn't been backing up with Time Machine (or a full backup which hasn't been overwritten) they are gone. Recreating the account won't being them back.
    If she has Time Machine, open (user)/Library/Mail in the Finder and then enter Time Machine. Navigate backwards looking for a folder named POP- and the name of the account. Use TM to restore that.

  • Could someone PLEASE tell me how to set up more than one POP mail account.

    I am soooo frustrated. Before I upgraded to Tiger I had no problems setting up my mail accounts. Now, I can only set up one POP mail account. I have three mail accounts that I desperately need to set up from the same ISP server, all POP accounts. On Panther and earlier, all I had to do was add the accounts. Now I have ONE POP account and when I try to set up another I get an error message that I already have a POP account set up. Why is this happening and what happened to the old system that worked just fine. I am so annoyed with this. It simply defies logic!!!!

    I don't know if this will work or not, but why don't you try using bogus pop and/or smtp server information when you initially establish the accounts with Mail's setup wizard? Just continue through the "warning: cannot validate server" messages that the wizard will give you. Then go into Mail > preferences > accounts and highlight each of the new accounts, one at a time, and try changing the incoming pop and outgoing smtp mail server information to what it is supposed to be?
    For the "Outgoing" server just use the pull-down menu, to select it, and when all accounts are done, go into that same pull-down menu and choose "Edit Server List..." to remove the bogus smtp server information.
    Incoming should be just renaming that pop server in the "Incoming server" field.
    If that doesn't work, I've got something riskier you could try, again with no guarantees, and that is editing your ~/Library/Preferences/com.apple.mail.plist file using either the Property List Editor that comes with XCode Tools (will launch automagically when you click on that .plist file if XCode is installed) or with the pico editor in Terminal, and possibly renaming some folders in your ~/Library/Mail folder, too. Again, start with the bogus server info, then find those entries in the .plist file and make changes there.
    Note: if not familiar with the notation, "~" means your "home" directory.
