Bug 332400

also netstat shows two open tcp connections to the server, so it must be something else.

And then somtime way later:

Unless KTcpSocket reads the data and hides it internally, the IDLE notifications simply never arrive at the client. I checked KTcpSocket's byteAvailable/stat/canReadLine as well as the sockets revc-q with netstat. We still get the "idle for too long" after 30mins, so the connection seems to be generally ok.

As we can see above, it seems as the server sends the "idle for too long", the pending notifications also get pushed through.

e.g. all routers from czech internet provider (UPC) are configured to drop every idle connection after 5 minutes and you can't change it. It will be good to have some option to set time inverval when akonadi reminds to server.

Is there any resolution to this? I'm seeing this on my kolab cyrus-imapd server as well. 

Seems to be server related as gmail still receives IDLE events

This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present?

If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.

I still have this bug I just don't login to this bug tracker very often, and I worked around it so I stopped being annoyed by it. 

If you configure an IDLE account and disable "Interval mail checking" it basically stops working after it times out, and doesn't reconnect the IDLE session. 

Thus, I have interval mail checking set at about 20 minutes and that seems to mostly work ok.

However, My phone using K9 _always_ receives mail instantly via IDLE (because I can hear the alert) and it takes a substantial amount of time for Kmail to show the same notification on my computer (both of mine) 

I'm pretty sure most of the time It's just waiting the 20 minutes to check of I'm between checking intervals, so IDLE is probably doing nothing for me still.

I'd be willing to work with anyone but I'm not sure where else to progress the bug on my own. I clearly have a configuration and server that is prone to this issue, but again other clients like K9 work flawlessly.

By the way I'm on:

Plasma 5.8.5
kf5 5.29
kdepim 16.08

And will continue to be on the latest of what rdieter is doing with Fedora 25+
