Mac Mail stops sending Mail

Ok so this problem is intermittent, but for the last few days its been constant. I'll be going through emails replying, then when i highlight an email all of a sudden it wont mark as read until i click it a second time. From then on all replys i send just dont happen, they dont get marked as replied to, it doesent say outgoing mail and when i search no mail has been sent. Shortly after that Mail will crash so ill force quit. I;ll re open mail and reply to the emails that wouldent respond and it will work as usual until another 15 emails later then itll all happend again. Its really frutrating me now as i cant get on with ANY work.

I re-booted and it went away... for now.  Will get back to you when it happens again so I can describe it.

  • G4-Tiger -When I use OS Classic, Mac mail stops sending  mail.

    My G4 Flatscreen has latest tiger, and latest mac mail, but
    when mail is open and I open classic and macwrite pro to get old documents, mail will not allow me to send or reply to email. it receives incoming mail fine.The Reply button just barely blinks, and the new mail button does nothing.
    3 trips to Apple Genius Bar only told me that the "genius" are only good at IPod repair for teenieboppers. They had no clue. I dragged in the G4, and after an hour they gave up.
    The only fix, after running all the fix programs, and archieve and install was a total erase and reinstall of Tiger and hence Mail. Now I am stuck, how do I get old documents that AW6 will not recognize, and Text Edit butchers so badly that it is useless. I have had to wipe hard drive 4 times in 5 weeks. this is getting very old.

    I think that you give less credit to 'most users' than they deserve. Speaking in generality confuses people and provides them little or no information. It also makes it appear that the person making the statement has no solid information and is merely "hand waving".
    Although 'most users' may not understand the technical details they don't want to be talked down to. They would rather be given the information and then digest it at their own rate. Saying that almost anything can cause interference with your wireless network will cause a lot of misunderstandings.
    I looked at the sites that you have in your post and they have a lot of detail especially compared to the statement I questioned.
    Let's examine your original statement:Almost anything that emits a signal and or using High or Low Frequency signals can possibly affect your Network if the conditions are right.Now, let's say that there are 2 people talking face-to-face. They are emitting a signal. As they talk they use both high and low frequencies. Their conversation will not affect the performance of your wireless network.
    That statement can certainly cause fear, uncertainty, and doubt (FUD) in those less technical that are using or contemplating a wireless network.
    Last but not least, In my opinion there are ton's of users that decide they want wireless technology, without doing no more than plugging in and expecting it to work without doing any homework on the pro's and con's of the technology and the use of the same.
    Sure, I agree with that. I don't think that has anything to do with this discussion though.

  • My Mac has stopped receiving mail. Mail is still coming through to my iPhone and my wife's iPad but is not appearing on my mac. I have mail from today on the phone but nothing newer than 18 Feb on the Mac. I have not touched any settings. Can anyone adv

    My Mac has stopped receiving mail. I have a mac.com address. Mail is still coming through to my iphone and my wife's ipad but nothing is coming through to my imac.I have mail from half an hour ago on the phone but nothing newer than 18 Feb on the mac. Everythng was working fine until recently and I have not touched any settings! Can anyone help?

    So I tried something else recently and it seems to have fixed the issue. My mail is now getting new mail again and refreshing after waking from sleep without having to restart mail. Give it a try and hopefully it will help you too.
    First, make sure your Mailbox List is visible (Shift + Control + M). Then select all of your inboxes, mailboxes, and folders (not just the root folder for nested folders, make sure to select them all). Then under the "Mailbox" menu, select "Rebuild."
    It may take a while to rebuild them all if you have a lot, but like I said it seems to have done the trick for me. I hope that proves to be more of a long-term solution.

  • It stopped sending mail and moving messages between folders, junk messages stopped being moved.

    Recently, Thunderbird stopped sending mail and moving messages between folders, junk messages stopped being moved.

    Further notes (different user, same problem):
    * This is a problem that started in Thunderbird 32
    * This involves both automatic (filter) moves and manual moves
    * This includes use of keys and hotkeys (the delete key, for example)
    * Restarting Thunderbird does seem to "reset" the problem... for a while. I notice the problem most when either I've been away from the computer/program for a while or when waking a laptop computer from a sleep or hibernation state.

  • Two days ago Mail stopped sending my emails.

    Two days ago Mail stopped sending my emails. I am using OS 10.10.2. Connection Doctor shows the connections as green. I can send from my iPhone in iOS, but from my Mack Book Pro, nothing sends. What changed? How do I fix this. I get an error message saying "The identity of smtp.cox.net cannot be verified. The certificate for this server is invalid. … When I ask it to connect anyway, or try the send again, I get a second message saying "Cannot send message using server smtp.cox.net… Authentication required."
    Connection doctor says "Connection to server succeeded; login not required."
    How do I fix this?

    This could be a complicated problem to solve, as there are several possible causes for it.
    Back up all data, then take each of the following steps that you haven't already taken. Stop when the problem is resolved.
    Step 1
    From the menu bar, select
               ▹ System Preferences... ▹ Date & Time
    Select the Time Zone tab in the preference pane that opens and check that the time zone matches your location. Then select the Date & Time tab. Check that the data and time shown (including the year) are correct, and correct them if not.
    Check the box marked 
              Set date and time automatically
    if it's not already checked, and select one of the Apple time servers from the menu next to it.
    Step 2
    Start up in safe mode and log in to the account with the problem.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    If the problem is not reproducible in safe mode, then it's caused by third-party "anti-virus" or "security" software. If you know what that software is, remove it as directed by the developer after backing up all data. If you don't know what it is, ask for instructions.
    Step 3
    Triple-click anywhere in the line below on this page to select it:
    /System/Library/Keychains/SystemCACertificates.keychain
    Right-click or control-click the highlighted line and select
              Services ▹ Show Info
    from the contextual menu.* An Info dialog should open. The dialog should show "You can only read" in the Sharing & Permissions section.
    Repeat with this line:
    /System/Library/Keychains/SystemRootCertificates.keychain
    If instead of the Info dialog, you get a message that either file can't be found, reinstall OS X.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it by pressing command-V. Select the line you just pasted and continue as above.
    Step 4
    Launch the Keychain Access application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad and start typing the name.
    In the upper left corner of the window, you should see a list headed Keychains. If not, click the button in the lower left corner that looks like a triangle inside a square.
    In the Keychains list, there should be items named System and System Roots. If not, select
              File ▹ Add Keychain
    from the menu bar and add the following items:
    /Library/Keychains/System.keychain
    /System/Library/Keychains/SystemRootCertificates.keychain
    Open the View menu in the menu bar. If one of the items in the menu is
              Show Expired Certificates
    select it. Otherwise it will show
              Hide Expired Certificates
    which is what you want.
    From the Category list in the lower left corner of the window, select Certificates. Look carefully at the list of certificates in the right side of the window. If any of them has a blue-and-white plus sign or a red "X" in the icon, double-click it. An inspection window will open. Click the disclosure triangle labeled Trust to disclose the trust settings for the certificate. From the menu labeled
              Secure Sockets Layer (SSL)
    select
              no value specified
    Close the inspection window. You'll be prompted for your administrator password to update the settings.
    Now open the same inspection window again, and select
              When using this certificate: Use System Defaults
    Save the change in the same way as before.
    Revert all the certificates with non-default trust settings. Never again change any of those settings.
    Step 5
    Select My Certificates from the Category list. From the list of certificates shown, delete any that are marked with a red X as expired or invalid.
    Export all remaining certificates, delete them from the keychain, and reimport. For instructions, select
              Help ▹ Keychain Access Help
    from the menu bar and search for the term "export" in the help window. Export each certificate as an individual file; don't combine them into one big file.
    Step 6
    From the menu bar, select
              Keychain Access ▹ Preferences... ▹ Certificates
    There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to  CRL.
    Step 7
    Triple-click anywhere in the line of text below on this page to select it:
    /var/db/crls
    Copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    A folder named "crls" should open. Move all the files in that folder to the Trash. You’ll be prompted for your administrator login password.
    Restart the computer, empty the Trash, and test.
    Step 8
    Triple-click anywhere in the line below on this page to select it:
    open -e /etc/hosts
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the built-in Terminal application in the same way you launched Keychain Access.
    Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window should open. At the top of the window, you should see this:
    # Host Database
    # localhost is used to configure the loopback interface
    # when the system is booting.  Do not change this entry.
    127.0.0.1                              localhost
    255.255.255.255          broadcasthost
    ::1                                        localhost
    If that's not what you see, post the contents of the window.

  • Gwia2012 stops sending mails

    After upgrading from GW8 (Netware) to GW12012 (OES11) my gwia stops sending
    mails after all 8 configured SMTP send threads are eaten up. This happens in
    a period of about 1 to 2 weeks and I found that used send threads aren't
    released anymore and the gwia send queue is filling up with unsent mails.
    After restarting gwia these mails are sent without any problems.
    With a low mail traffic of about 300 mails in and 50 mails out per day I
    used the default smtp thread values of 8 (send) and 16 (receive).
    Any help is welcome!
    Cheers, k.

    The challenge with such a script is, 'What counts as dead?'. I have
    seen agents that are running and responsive to tests, but some part has
    been non-functional such as in the beginning of this thread. The script
    Thomas pointed us to (Thanx Thomas, it is certainly useful) would
    probably not help K for the problem he/she is dealing with.
    Rereading Danita's post in this thread really looks to me like just
    scheduling a simple restart of the agent weekly just to get through
    until the problem is resolved. Perhaps you mixed up threads as she
    certainly alluded to such as script in another thread (GWIA dies avery
    2 -3 weeks).

  • SSRS Subscription LastStatus "Failure sending mail: Failure sending mail."

    SSRS 2012, SQL 2012 SP2. 
    We have about 50 different daily subscriptions that go out.  In the last month or so, probably over 30% of SSRS subscriptions are getting this error and no e-mail is sent.  I have tested out the reports with the parameters and the reports run just
    fine on demand for both the user and myself.  I'll change the subscription forward for testing, and it will intermittently work or fail even when no traffic is hitting our database so I dont think it's a matter of performance. 
    I see nothing in the error logs, and I see nothing in the logtable 2, or 3 in ssrs as suggested by a few MSDB sites.
    The only spot I can even see this error, is when viewing the subscription. I have done LOTS of searching, and most people get a helpful error after "Failure sending mail" where as I only get 'Failure sending mail: Failure sending mail"

  • Mail stops accessing mails

    Mail stops accessing mails in most cases after downloading many of them. The rest will follow then and when. I am not sure if there is a rest because I forget the number of the downloaded mails when the procedure is finished.

    Welcome to the forums Oliver... good work at narrowing the problem down so far!
    Try dragging this file to the Desktop and reboot...
    /Users/nnnn/Library/Preferences/com.apple.mail.plist
    Might also pay to clean caches, I use Applejack, but there are many. The log makes me think cache especially.

  • After hotmail come up on my screen I am not able to open mail or send mail?

  • TS3276 Well it happened again. Why does my apple me account stop sending mail for no apparent reason. One minute it is working find and 10 seconds latter you get error messages that it does not recognize your password. I am really fed up with the mail sof

    Things were going well. Mail was working fine and then the following error message appears out of nowhere. I had not changed any settings. From that point on all efforts to send mail failed, and the error message appeared even thought I used the password to log back in after I quit. Now, an hour after the problem started it takes my password (on the second try after the error message appears) once and sends a test message. Then, one minute later it gives the error message again and refuses to send anything. Why is mail so inconsistent? What can I do in the future to address the problem?
    Error message reads "The SMTP server "xxxxx" rejected the password for user "xxx" Please re-enter your password or cancel.
    When mail does work again. Should I click the remember this password in keychain or am I just asking for more trouble?
    I'm writing this using my IMac computer in a different room. The error also occurs on my powerbook running my new MacBook Pro 12 inch.
    Fed up Mac user.

    I"m no expert but this used to happen to me all the time (stop downloading, asking for my password, nothing downloading, walking away- 24 hours or more later, all is fine, only to later start all over again)
    Well, i gave up for a long time and stopped using that account with mac mail and only accessed it online..recently went and changed the pop3 to only pop and now it works beautifully and seamlessly. Don't ask me why or how, but it does so thought I'd share.

  • Mail Client stopped sending mail via googlemail after changing password

    I changed my google mail password.  Now, I am getting smtp.gmail.com failures on both my iMac and my Mac Air.  I have updated my google password on all my devices. iPhone and iPad work fine but neither computer will send mail. Running Yosemite 10.10.1 on both computers.  Also tried resetting Captcha (?) per similar issues on google threads...did not help. 

    You do not need to delete your account.  The trick is that there are TWO places to put in your account password.  You probably fixed it in the obvious place, and your incoming mail works fine.  Now you need to fix it for your outgoing mail:
    Settings > Mail > your account > Outgoing Mail Server > Primary Server >Password
    and suddenly your outgoing mail will work again  :-)

  • New mac - can`t send mail

    i have just gotton a new mac book pro, and have imported everything from my old mac. everything seems to be ok, except i can not send mail, only receive and read..... i have also tried deleting my accounts and reinstalling them, but it did not help. anybody who can help me with this??

    With the caveat that I'm not sure why this exactly works, I had a similar problem which I just recently solved.
    My laptop would send and receive mail fine when connected to a modem. But at another location I had access to a broadband connection. For the longest time I could only receive mail but not send from that location. Then I had to borrow a friend's laptop for a while after mine crashed. I set up the borrowed computer for mail and to my surprise I found I could both send and receive from my wireless broadband location. After I got my own laptop back up and running, I found the old behavior of not being able to send mail was back. Determined to find out why, I compared the preferences>accounts settings of my laptop with my friend's. I found one difference, changed it on my laptop and voila … it now works.
    The key was in the server settings, found at the bottom of Mail's Preferences>Accounts. Clicking that button brings up another window called SMTP Server Settings. It seems a default for server port is 25. This, for some reason does not work, but 587 does.
    I honestly do not know how 587 was entered into my friend's laptop, but when I changed mine from 25 to 587 it worked. You should note the warning not to change these settings without consulting the System Administrator, but I'm a single user, so I just went ahead and experimented.
    Good luck

  • Mac Mail stops recieveing mail with Gmail Accounts and Google Apps

    Hi,
    We're having some chronic issues with our corporate Google Apps / Gmail service when used with Mac Mail. Regardless of the OSX version... when it's not one thing it's another. It's nice to see that 10.9.4 finally correctly inserts the proper, full username in the SMTP field for Google Apps users.
    We still have some problems where users stop receiving mail silently in the middle of their workday. It wouldn't be such an issue, except that Mac Mail pretends nothing is wrong and suddenly the person realizes they are 3 hours behind on their emails. Magically, quitting and re-opening mail resolves the issue. Even more disturbing, is this article on apple support which lists this stupidity as the official workaround
    OS X: New email messages not received until Mail is quit and reopened
    I suppose one could argue that Outlook 2011's integration with gmail accounts is even worse. There's something to be said about "AirMail" being the #2 app in all the appstore currently. Clearly Apple and Google aren't putting their best foot forward to make this work.
    I guess what I'm looking for is something concrete other than "Restart Mail to get mail coming in again". Is there some workaround to see the connection status to see if something is stalled?

    Googles version of an IMAP system works poorly with most clients. If you are going to use it then choosing a client that works the way Google wants them too is a wise course.
    Of that breed MailPlane is easily the best, AirMail is a solid second.

  • Outgoing mail stopped sending

    Hello, you wise apple ones
    could you help me get my email back running properly?
    Powerbook G4, running OS 10.4.11
    email server with yahoo
    pop account/ smtp
    incoming mail fine but outgoing goes to outbox and sits and error message comes up
    saying that "the sender address has been rejected by the server at yahoo.co.uk
    what do you think I can do to fix it?
    Thanks
    Elaine

    Gmail allows unrestricted free access. There others:

    how am I managing to send mail then? albeit erratically?
    perhaps what happened in US is happening in UK
    That's what I'm suggesting, but I could be wrong. The link I posted to the Yahoo page us from the US help pages (at least, the url includes .../us/...). You might try searching Yahoo help for more info. Or just switch to Gmail
