    Default Apple Mail hangs

    We are using the latest version of Zimbra with a number of various Macs on various versions of Mac OS X. For the client software, we are using Apple Mail, set to read mail from Zimbra using IMAP.

    Half of our users are having great success. Half are having issues with Apple Mail getting "stuck" while synchronizing mail with the server, and no new mail can be read or sent when this is happening (rendering the client software useless). Force quitting the Mail.app program and restarting it resolves the issue every time, but only for about 24 hours, when it happens again.

    We run a large variety of desktops and laptops, running everything from Snow Leopard to Mountain Lion. There seems to be no rhyme or reason or pattern to the users that are having issues, except that they are the heaviest users of mail (ie, most number of messages stored on server). However, the issue is not always user focused, sometimes it is machine specific. That is, a user can login from Desktop machine and get all mail, but the problem occurs when the login via their Laptop - all on a repeatable basis [its not random].

    If the users logs into Mail via webclient, all emails, files, and folders seem to be there, so it seems to point to an issue between Apple Mail and Zimbra, but that doesn't explain why only half my users are having problems.

    I would like to find out if anyone else is having similar issues (or resolutions) to users in similar situations.

    My reply isn't going to help much but I probably force quit Mail.app three or four times a day. I use it, but I don't like it.

    Since my address book is sync'd on my desktops, a laptop, and my phone, I've just stayed with it.

    You may want to look at the max number of concurrent connections you are allowing and adjust as necessary. Apple's Mail.app will open up +10 connections at once.

    "You may want to look at the max number of concurrent connections you are allowing and adjust as necessary. Apple's Mail.app will open up +10 connections at once."

    I am assuming you are suggesting increasing the number of simultaneous connections on Zimbra server? It may sound like a dumb question, but our server is hosted for us by a third party, so I have to ask the correct questions to get them to change anything...

    I have my server's maximum imap connections set to 700.

    The hoster can check that value by entering (as the user zimbra) the following command :

    Code:
    zmprov gs my-server.whatever zimbraImapMaxConnections
    Note : We have 600 users and probably 90% use Apple Mail.

    Thanks. May I assume from your first comment that this did not resolve the hanging issue for you?

    That "adjustment" helped a lot, but I still occasionally have to force quit Mail.app. I've gotten accustomed to it.
