Disable the Push IMAP (IDLE) email in macOS Sierra

Does anyone know how to disable pushed IMAP email in macOS Sierra? In previous OSes, this option was in

Mail Preferences -> Accounts -> {chosen account} -> Advanced tab

and the option to change this behavior was at the bottom:

[√] Use IDLE command if the server supports it

I can find no representation of this option within macOS Sierra, nor can I find a way to change this option manually in El Capitan via 'defaults' or a specific preference file to attempt to replicate this behavior manually.

The changing "Check for new Messages:" option has no effect on this behavior.

Any assistance is most welcome!

When a new email arrives at your mail server, it is automatically delivered (pushed) to your email client. In a nutshell, if your email service supports push email and you have a client which supports the same, you'll receive emails instantly.

You can select work offline if you don't want to receive regular downloads.

I am well aware of that feature. It's technical name is IDLE, and I am asking how to turn that off in macOS Sierra, as has been possible in all previous versions of OS X. I do not want email pushed to me.

Other than selecting to work offline, Apple seems to have removed that option.

I suggest you send Apple Feedback.

Bummer, what a farce Mail has become. I left feedback, but that will fall on deaf ears as usual. I continue to find additional issues with this latest version of Mail, including it ignoring that a contact is in the Contacts app and still marks it as spam. What a joke…

Microsoft Outlook 2016 still has the option for IDLE. You might want to check out these email apps: Postbox and MailMate. Both have demos. I don't have installed to check options.

MailMate does not support POP.

Note: Microsoft Outlook does not sync to iCloud contacts and calendars.

You can select work offline if you don't want to receive regular downloads.

Turning on the offline mode has been broken since El Capitan. I have emailed Apple a few times about this and spoken to one rep at length, but there seems to be no fix in the works.

The problem is that taking an account offline does not keep the account offline if you do anything within the inbox. Just clicking on an email in the inbox will take the account back online - and thus initiates automatic downloads again.

I have been using Mail for nearly a decade, and Take Accounts Offline has always kept accounts fully offline (no sending or receiving) until the user manually turned the accounts back online. But since El Cap any action within the Inbox has taken the account online.

This was causing enough damage to my workflow that I reverted back to Yosemite. I really do hope Apple fixes this. But  I don't think enough people rely on this feature to have spoken up about it.

I have another reason to turn off Idle: Mail appears to be abandoning (but not closing) idle connections and creating new ones. Over time the connections to the server pile up, to the point that they exhaust the server's allowable connection count.

Perhaps there is a config file in the guts where this can be turned off? Doesn't have to be GUI.

I have just realized this is a big problem for me as well - would love to see this fixed or at least an explanation as to why that feature was removed.

Based on Re: Limit Number of IMAP connections to Mail Server ...? I tried to add the key (which was not present in the plist file) in a Sierra installation but it made no difference. Large numbers of smtp connections keep piling up on the server.

Another iMac on the same network also using Mail to connect to multiple accounts on the same mail server does not show this behaviour. It hasn't upgraded to Sierra yet.

My website crashed today with 500 internal server error, due to IDLE processes from IMAP settings. As Apple have for some obscure reason removed this option to disable IDLE processes I have switched back to POP3 while I look for another email client, that is more stable than Apple Mail. Hopefully I can get my 'business' website up and running again quickly.

Apple Mail seems to crash and hang far too often these days. I upgraded to Sierra last week and it just seems to be more problematic.

Hope this helps others having same problem.

Has there been any movement on this problem?  It is a big issue for me.

Big issue for me too!

Big issue for me too! Some mail accounts should be checked regularly, and some only on my request...

I have been having this problem as well while trying to design a wordpress blog. Frustrating! Mail got caught in a loop with my web servers.
