After kmail 4:6.12.0-0neon1 upgrade my kmail messages totally messed up. I used to store pop messages in local Inbox folder, also have some folders for filtered forums messages, some separate imap accounts, etc. Now forum folders has some messages that used to be in Inbox, also has messages from absolutely different imap account. Some messages in Inbox are duplicated now, some missing. Situation looks like there was tornado in kmail folders, everything messed up. Does anyone else experience that? Maybe have clue how to fix that?

I suggest you also post this in the Neon forums. I haven't been experiencing such issues here, so far. You may want to try running "akonadictl fsck" in a terminal to see if it manages to fix the problem.

I don't have the same issue because I do not use POP, but I recently saw "deadly embrace" happen _and_ yesterday I saw message headers in my inbox have the content of messages N farther down in the list. At first I thought it was some kind of sorting problem since sort newest first and some of the content was for messages which appeared to be the same N from the bottom of my display as the selected message was from the top. In the end I shutdown and booted a different computer then used Thunderbird to clean up my inbox. My mail is on an IMAP server.

Last night I saw the "deadly embrace." There appears to be absolutely no way to shut KMail down. When I close Kontact and it disappears from the task bar I want it to stop _everything_ it was doing. I close Kontact (or any other PIM) because I am opening up FocusWriter, Libre Office or a text editor and I want to focus completely on what I'm writing. I don't want to see new mail notifications every N seconds. I haven't found a way to get KMail to stop doing this.

"Deadly Embrace" may or may not be related to you problem, but, my office machine was left running and yesterday evening I booted my HP laptop with same Mint 18 KDE and KMail to check email. New messages kept popping up and disappearing. I would delete one or more messages with the delete key, watch them go away from inbox only to reappear 2-3 seconds later as highlighted new mail. A few seconds later they would gray out, then they would disappear as something else I had just deleted started the same journey.

Even though I have things sorted in my inbox from newest to oldest, the date and timestamp associated with the messages were all over the board. The list kept changing content and order making it difficult to navigate.

It all came to a head with a delivery confirmation notice from Sears. It was the newest message in the list. No matter how many times I deleted it with the delete key, it kept coming back as a new message. It didn't go through the repeated delete path of the other messages, it was Jason, the email which could not be killed. I finally gave up and powered off. Today I put Linux Lite on the laptop. We shall see if KMail simply does not play well with another KMail or if KMail was never taught to share.

I realize there will be a request to put this in its own thread, but, I feel it "could" be related to your problem. If you or someone else accessed your email via some other method, say a Web interface, while KMail thought it was Highlander, it could have set up the same thing I was seeing. Will know more tomorrow after I try accessing email tonight using Thunderbird on my laptop. If the same mismatched header to content and deadly embrace happens then as much as I love having KATE I will have to jump distro and desktop. My office machine is never turned off and I access email while on the road from various interfaces. They must all play well together.

Could be related to my problem. Messages I delete from "wrong" folder -- I mean, from folder, where these messages shouldn't be at all, reapears after some time.

I don't see the issue here (openSUSE Tumbleweed) so I suspect a packaging fallout.

https://bugs.kde.org/show_bug.cgi?id=375149

Somebody filled bug report with similar problem like I had. Seen on KDE Neon, Gentoo, OpenSUSE. Definitely not packaging issue.
