Kmail triggers inbox realod every few minutes

After update to 6.400 my app started to reload all messages in my inbox imap account. It seems that it does something on the server, because my Thunderbird client does the same after it happens on k9mail. I have upgraded also to the latest version 6.5xx and behavior is the same. I have done a fresh reinstall. My server is Icewarp.

I have noticed, that this behavior becomes a bit less often if I set “push folders” and “sync folders” setting to “all folders”.

Is anybody reading this?

Yes. Somebody is reading this.

Me too. I am not yet fully clear what happens to you exactly. Also maybe additional a debuglog might help
