Mac Mail - IMAP setup - Large attachments are corrupt

Mac Mail - IMAP setup - Large attachments are corrupt
Attachments open fine in webmail
Mailbox rebuild does not help
Appears files over 500k are affected
Multiple users affected
Backend is GroupWise 7
So, I see several posts on this topic, with no solutions.... Is this a known issue according to Apple? If so, can some point me to the official release notes/ bug report??

I have the same problem. When I look at the message with Entourage, I found out that while under IMAP the attachment is not fully downloaded from the exchange server. Entourage gives you the choice to download this file. When I select, the file comes down and opens OK. I heard that some clients have a max size download setting for IMAP but Mac Mail does not. Anyone know how to get around this?

  • Mac Mail IMAP shows read message when already read from other devices

    Mac Mail IMAP is setup on custom domain ([email protected]).  When I open an email message through my iphone it shows it was read.  Then when I go into the mail app on my iMac, it shows the message is unread.  It still shows unread hours later and even when I click the "Get Mail" button
    How do I make it so that Mac mail syncs when I check mail through other devices?
    Thank you

    Open Terminal in Utilties and copy/paste
    This will send the attachment embedded inline. (This works in Snow Leopard, but not sure about Lion. Do a test first. If it doesn't work, just google "send attachment embedded + Lion." You don't actually have to send the message to see how it will appear.)
    defaults write com.apple.mail DisableInlineAttachmentViewing 0
    To reverse the setting, change the 0 to a 1
    However, whether this will work or not will depend on what the e-mail client on the receiver's end does with it.

  • When deleting a user created folder from On My Mac in Mac Mail the sent messages that are part of conversations that reside there are not deleted, only the received mail gets deleted.

    When deleting a user created folder from On My Mac in Mac Mail the sent messages that are part of conversations that reside there are not deleted, only the received mail gets deleted. Any way for both the received and sent mail that resides there to be deleted?
    I create a lot of project folders where i keep all my conversations regarding the project. Once the project is finished i would like to just delete the folder and get rid of all the emails associated with it but when i delete the folder i've noticed that only received messages are deleted. Now I am stuck trying to sort through my sent folder for messages that were returned there after the conversations was supposedly deleted.

    Mail/Preferences/Viewing - un-check include related messages, delete the folder, then go back and reset yo include.

  • Limit in Mail on receiving large attachments?

    Noticed someone else had a problem with receiving large attachments in Mail and my friend and I also have it now.
    My question is if anyone knows of a limit to size for recieving attachments in Mail. I noticed that Apple has set a default 10 MB limit on their server versions and thought maybe this is so also in ordinary OS X Mail? If so -- how do I change this in OS X?
    (It is really ridiculous that one should not be able to send a small 15 MB file with e-mail any longer -- it is not like we are all getting slower connections, less hard drive space and slower processors all the time, so why does things like this happen?)
    Yes, I know the problem is not releated to ISPs, Mail Servers, Firewalls as I have tested for that in most respects. (No problem sending such a file nor downloading it via web mail, etc.) It could be related to IMAP and Apple Mail.
    /Jerry (in Sweden where you cannot specify decimals on paper sizes under Mac OS X ... )

    Yes, I know the problem is not releated to ISPs, Mail Servers,
    Firewalls as I have tested for that in most respects.
    Yes it is related since this is not a limitation or problem with the Mail.app or with any email client.
    Most ISPs and email account providers have limits on overall message size for received and sent messages similar to the .Mac account message size limit for received and sent messages.
    Your ISP or email account provider may not have such a limit (which is unusual) but the recipient's ISP or email account provider may impose a limit.
    Have you checked with your ISP or email account provider for this account regarding a message size limit imposed for received and sent messages?
    In case you aren't aware, message attachments must be encoded before being sent. The Mail.app uses MIME 1.0 for attachment encoding which is the internet standard. The pre-encoded size of the attachment is increased by 50% or so after the encoding process. A 15MB file will be roughly 22.5MB after the encoding process.
    Check What is the maximum size of email attachments? for information on the attachment encoding process.

  • Mac Mail - IMAP Gmail

    I have a domain set up for work which directs email to my gmail account. This works a treat and I can send and receive email as if from the domain name.
    I have recently bought an iphone so set up my gmail account to be IMAP, hoping I could use it for my phone and macmail. I can receive the emails through both, but can only send using the dummy account name with gmail.
    All I want to do is send email using mydomain.com through mac mail and my iphone, using gmail as a dummy IMAP account. Ever get the feeling you're not explaining yourself too well?! Aargh! Hope someone can help though.

    I'd follow WBW advice, but here's some more info.
    What gmail does to be able to send as a different "FROM" is just authenticating you as being the owner of the "FROM" you want to use and then naming it as they will, just like you can post a mail on the post office and say it came from anywhere you wish - you just change the "FROM" field on the letter.
    It also says it's coming from gmail, but most mail servers just ignore it or tell you "delivered by" using some SMTP standards.
    Both Mac Mail app and iPhone do similar stuff. You have to first setup an inbox account to be able to use it as a "FROM". Then you can even send it through another server, gmail in your case, and say you're sending it from the other domain - if that server allows it (which most do, including gmail as you know).
    You can configure as many SMTP as you wish on either, but you just have to do all that - just like you did on gmail. For each one you'll have a full mailbox configured.

  • Mac Mail to Gmail truncates attachments names and removes exstenstions

    I have a user that has mac Mail 2.1.1 and is on OS X 10.4.9. Sometimes when he sends mails to his colleagues, the attachments are truncated and the extensions are removed. For Example:
    In Mail, he attaches a file called "Heid Survey.doc". Mail sends the file and the Sent mail looks ok. On a windows machine, using firefox and gmail.com, another person checks the email and gets an attachment named "heid". It does not recognize it as a word file. If the attachment is downloaded and the .doc added to it, it will open. If the same recipient checks the mail message in Mac Mail, the email and attachment come through fine.
    I have tried this using both "Send Windows Friendly attachments" and with out it.
    This does not always happen he reports, but I was able to recreate it with my gmail account and his laptop consistently. My Mac Mail shows the attachments fine as well.
    I also tried to zip the file before sending it to gmail, and gmail recognized that it was a zip file, but when I tried to save it to the desktop on windows, it only saved the truncated version after gmail un-zipped it.
    I do not know if this is a Mac Mail or a Gmail issue. I am not sure what is happening to these messages. Can any shed some light or give me some troubleshooting tips? Anything that I can try would be great. Thanks!

    It has nothing to do with the contains. I believe it's a bug, and if you search translators lists like Systran's, you will discover this issue is spreading virically. Do not know what happens. What is known about this by embattled Mac users who now have to stop using Mail app: the phenomena begins out of the blue, one day works, one do not, it affects every file type (seems to be a problem with the name only, nothing to do with ASCII issues) and also, activating the "windows friendly" part does nothing. My case is really funny because I have one mac account with several mail accounts included, and it began with the main one (the others sent files ok) and now every account is affected. My boss is crazy with this. After a certain amount of time in the gmail account, the names appear fully sometimes, but obviously you can't tell a client, "sorry, you have to wait one day to check your mail, because I'm using Mac and it looks great, but it can't send attchments". Google says it's Apple's error, and Apple do not answer.

  • Mac mail not showing jpg attachments after yosemite install

    I use Mac Mail and have recently upgraded to Yosemite. 
    Since upgrading I can no longer view jpg images sent by email from my security camera system.  They used to be shown within the message, but since the upgrade to Yosemite they're not shown in the message anymore (well, they are shown in about 1% of messages), even the attachment won't open after saving to desktop.
    When I try opening the attachment after I have saved it, it says it may be damaged or use a file format that Preview doesn't recognize.
    I can view these images when using outlook on my mac, but preferred the Mail app, as it was easier to view the images in Mail.
    Any suggestions on how to fix this?

    I have the exact same issue.
    Since upgrading I can no longer view jpg images sent by email from my security camera system.  They used to be shown within the message, but since the upgrade to Yosemite they're not shown in the message anymore.
    When I try opening the attachment after I have saved it, it says it may be damaged or use a file format that Preview doesn't recognize.
    I wonder if it has something to do with the file name
    Here is an example - 02_20141022141258.jpg
    I have no issues viewing the images on my iPhone or iPad

  • Mac Mail in 10.6.8 keeps corrupting

    My mac mail keeps corrupting and I keep running my disk utilities to fix the preferences which helps for a day or so the back to weird stuff, where when typing characters jump around or it won't let me type at all, then can't send the message after battling through it. Had to shut off one of my mail boxes because it could connect to the server and would just keep spinning. Tried to reistall Snow Leopard and it helped for a couple of days then back to same old. Also rebuilt the boxes.
    What should I do to get my mail functioning again?

    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    Any improvement?

  • Problem with Mac Mail-iMap server on Hosting (Overloading Server)

    Hello, I just created an account with HostGator for my business and we have 6 emails. We have imap email and our account allows us to check email once per minute per email. We have it set up to check every 5 minutes so this should not be a problem.
    They then told us that there was a problem with it checking more frequently and also overloading the server by issueing 'multiple imap commands per email, 3 to 4'. I can view our server processes and sure enough each email is showing 4 imap commands. I unchecked 'use IDLE command" since I know IDLE command has something to do with it checking frequently for email.
    Unfortunately we have 3 processes running on our website so once we had 24 for the 6 emails that goes over our limit of 25 and our website goes down. For now we have had to turn off most of our emails except 2 that we receive most email at which is causing major problems.
    When we talked to HostGator that question was "Do you use Mac mail? Mac Mail is knowing for doing that". Since I only use Mac's I don't want to have to switch to Windows for email or use another email program like Entourage or Thunderbird. This is a frustrating issue and when I did research on Google I saw a lot of other people having this issue but didn't see any answers. Any ideas what is causing this and how I can fix it?

    Hi,
    IMAP IDLE is not the problem - it is even good! http://en.wikipedia.org/wiki/IMAP_IDLE

  • GoDaddy Mac Mail IMAP...HUGE delay receiving email in mac mail

    issue: (only with godaddy IMAP email accts in Mac Mail)
    i can send emails no proplem
    the problems is receiving them...there is an enourmous delay-up to 8 hours!
    things i have done/figured out:
    on the godaddy email client all is good
    on my iphone the account works
    i set up an account in entourage and the account works
    i upgraded to snow leopard
    i deleted the accounts and recreated them
    here is the rub...i figured out a "work around". if i manually "sync all accounts" in mail and then click on get mail the mail comes in immediatetly or if i delete an email in one of the accounts and then click get mail the mail comes in immediately. but Mac Mail won't retrieve email other wise.
    I know that this is a problem others have expereineced but i have not been able to find the solution
    i believe that it is an issue with Mac Mail and perhaps the IDLE feature (disabling IDLE does not help that much)
    i have spent countless hours on the phone with godaddy and today they told me that the problem is a mac issue and therefore i am on my own.
    any ideas???

    Okay - I fixed it.  Here's what I did.
    - Deleted the entire mail folder inside my Preferences folder.  ~/Library/<userfolder>
    - Kept the files in the trash just in case, but didn't need them
    - Rebooted
    - Opened the System Preferences
    - Selected "Mail, Contacts & Calendars"
    - Verified the previous account was gone
    - Clicked Create
    - Created a new account and then opened Mail
    - Voila! Email
    Note - if you trash the mail folder inside Preferences, it will delete any local emails.  All my email is IMAP and I never store anything locally, so everything syched right back when the account was recreated.
    Good luck.  Hope this helps.

  • Mac Mail IMAP root folder

    I am using a Treo650 smart phone (not sure about the "smart" part...) to check .Mac Mail. In the phone's mail app (VersaMail), in order to synchronize the Sent & Deleted messages, I need to enter the "root folder" name. What is this name? Thx. in advance for any help.
    Mac TiG4   Mac OS X (10.3.9)   Palm Treo 650

    Thanks. I tried that, but then there is no synchronization between the Deleted, Sent or any other Mail folder. It does work though, as a simple way to get my messages on the go.

  • Mac Mail IMAP Problem: Actually Seems to Be an AOL Problem

    For what it is worth, After much futile tweaking, it would appear that what I, and a number of other users thought was a Mac Mail problem, to wit, the need to Offline>OnLine to get mail, may actually be a problem with AOL (and possibly other e-mail services).
    Apparently, AOL is manipulating its outbound mail port(s) to limit server demand. I've reached this conclusion after noticing how on weekends and nights, mail seems to work fine with AOL.
    Comments anyone?

    Open a Finder window select your Home folder in the Sidebar on the left. Then open the Library folder, then the Caches folder, then the com.apple.Safari folder.

  • Mac Mail sending messy code attachments to windows

    I've sync 6 different mail accounts to my Mac Mail, but what it troubles me is that when I send Chinese emails with attchemnt (in Chinese too) the reciever Widonow users keep getting messy code with somthing like (鍛@?鍗＄墖.docx).
    I've been look every where on Google can't find any good solution. I know that changing my Text Encoding works but I can't set it to defualt
    I know there's an updates that windows can download so that they read mac's uni code, but I can't find the download link.
    If I switch to Office Outlook would I still get this problem? or is there any better way that Apple can help me to solve this?

    To thoughs just been searching, I just came across a app that actually solve this problem (well at least for Chinese attachment).
    It's a new app develop by tencent called foxmail (http://foxmail.com.cn) it works fine for me.
    you guys can go check it out. But this app's interface isn't as good as mac mail, but at least my colleagues stopped complaining at the mess code problem.

  • Merge Mac/Mail/IMAP and Dell/Outlook/POP

    A friend called me with a problem that wads of her email were going missing from Mail.  After spending a while there it turned out that she uses email on 3 platforms
    MacBook Pro, Mavericks, Mail, IMAP
    iPhone 5, IOS7, Mail, IMAP
    Her old Dell with Outlook and POP
    She is using whichever system is handiest.
    Now I know precious little about email but it seems to me that the missing Mail from the Apple platforms is ending up on her Dell because it's got POP.
    Q1.  Does that seem about right?  It looks like the missing mail is there from a cursory scan.
    Q2.  Assuming that's correct, is there a way to fix this: to get the mail off the Dell and on to her Apple systems? 

    Having slept on it, I wonder: Could this be solved by
    creating an IMAP email account on the Dell alongside the POP one
    copying the email subfolders from the POP account to IMAP
    allowing this al to percolate via the server to the MacBook and iPhone
    Suggestions?

  • When I apply a mail rule to move a message to a different mailbox, large attachments are unreadable

    I have a rule in Mail: Move messages that were sent to a particular accout, to a particular mailbox. It moves the message like it's supposed to but if there are attachments over about 1 MB the attachment is no longer there, and instead there's  a bunch of code in the body of the message. With smaller attachments, the message appears in the new mailbox with the file attached, just as expected. Anybody know what's up? Thanks, Bob

    You can't simply feed it some arbitrary script to execute, you have to write a handler that Mail can dispatch events to. This generally looks something like
    using terms from application "Mail"
    on perform mail action with messages theMessages for rule theRule
    tell application "Mail"
    repeat with suspectMessage in theMessages
    --do something
    end repeat
    end tell
    end perform mail action with messages
    end using terms from
