--- Comment #2 from Macxi <terraagua at gmail.com> ---
I'm checking what the possible causes of this error. with migration from kmail
to kmail2.
If I made a mistake and if there's any bug or something that can be improved to
avoid that.

Error that I may have committed:  I configured Kmail as POP and I imported the
messages in a non-recommended directly from the folder .kde/share/apps/kmail in
a very large number of messages (more than 10,000).

I have not used the mechanism of export (folders with messages) from Kmail
because did not know existed, so I may have caused this error to have
improperly imported messages.

What can be improved in Kmail2 :There is no clear guidance on how you can
export messages. To export, you click on Kmail folder, and right-mouse button,
select the "Archive Folders", which will create a compressed archive (zip, tar,
etc.).

Akonadi gave warning error when I moved  Kmail folders
