    EDIT: I've upgraded to Sierra and I'm pleased to say that the Mail issues I've had are completely fixed!

    I'm having serious problems with Mail in El Capitan, with the IMAP connections always timing out until I restart WiFi. This makes Mail totally useless because it can't receive emails.

    Has anyone had this issue in El Capitan? Did the issue get fixed in Sierra for you? Does anyone have any issues with Mail in Sierra?

    I'd normally hold off upgrading because who knows what problems it will cause, but if it actually fixed a problem I currently have, I may as well upgrade.

    I had those issues across a few versions of El Cap as well as the first few Sierra betas. As of about Beta 6, I haven't encountered it. Whether it stays gone, or will go away for you during the update, I cannot say. Seems to be a rather persistent bug with Mail.app for certain users.

    I had this issue happen daily with both El Cap and the early versions of Sierra public beta. Haven't had issues at least for a month now.

    I just installed GM. All smtp servers in mail app are showing offline. When I go into edit mode none of my listed servers show there though they show in the pull down menu in accounts preferences. When I try to add new server it auto deletes in few seconds. incoming all POP accounts are OK.

    Also tried finding the plist file to manually edit. Even there cannot find the server settings entry even for the server I managed to save finally after many efforts.

    I rebuilt a MBA last night with Sierra and a number of IMAP accounts which were working previously (on GM Sierra) have now stopped. They've been picked up from another machine via iCloud (a system which I'm very suspicious of) but even going in manually and making sure details are correct, the accounts just won't stay online.

    At times, MacOS seems to be trying to be clever and changes the mail server to a form of the email address i.e. mike@xxxxx.com rather than the info I put in there, mike@ispdetails.com.

    Any ideas?

    I recommend setting up everything as manually as you can with Mail. It has a way of auto-detecting settings and then it won't let you change them. I know that with Gmail, the trick is to set up a brand new "Other" account rather than a new "Gmail" account, and type in everything manually. Not sure if that helps.

    For me, Sierra has definitely fixed every problem I had with Mail in El Capitan and Mavericks. Basically Mail didn't work at all, and now it works fine, I can send and receive emails again. But of course this is just my specific case.

    When I think about the future, I don't imagine self-driving cars, artificial intelligence, or thinner iPhone. I just imagine a world in which we can continue to do the things we can already do today, like get email and listen to music. While it doesn't sound like it, it's a very ambitious dream.

    I've had few/am having no issues with Mail. Occasional gmail 'offline' but no other major issues here. Shame Apple hasn't sorted attachments out though.

    Is there a way to stop the Mac learning about other email addresses you may have on other iCloud devices? That seems to be the start of the problem....

    With El Capitan on one of my Macs I had the problem that gmail was offline most of the time. With Sierra the problem has disappeared. Now I have no issues with Mail.
