Hi all. Lots of trouble - of course - with the new kmail (I assume
2.1 was rebranded as 4.7 when kde 4.7. was released?).

Anyone know what could cause this:

kmail shows an almost empty sent-mail folder. The messages do
exist in ~/.kde4/share/apps/kmail/mail/sent-mail/ but only
the three I most recently sent show up in kmail.

Updating kmail-folders does not help ...

Here's another and scary thing.

I sent a message but if I grep for its contents in the sent-mail
folder there is nothing there. But this message does show up
in kmail's sent-mail folder.

Guess where I find the content of the message? I find it in
~/.local/share/akonadi/file_db_data

What is going on here??!!

Is kmail not storing my mail in the proper location?
How do I tell kmail to use the normal mail location?

As an experiment, I copied the three visible sent-mail
messages to another, empty, folder. After the copy,
the ~/.kde4/.../mail/emptyfolder was still EMPTY.

The copied messages turned up in the .local/...file_db_data
folder. WTF?

I am really at a loss here.

sorry I can't ask a more coherent question. I think some of
the problem is not me, but the state of kmail

as a follow up to my post. I was able to import my
sent mail into a different folder. I cannot copy them
into the sent mail folder however, but at least I can
see them in kmail

After the import, all the messages were indeed stored
in ~/.local/share/akonadi/file_db_data

It strikes me as dangerous to have mail stored in more
than one place

I thought akonadi just indexed the mail but it seems to be
actually storing it and removing it from the folder which
kmail settings designates as the mail storage folder

I don't think that is very good behaviour

It's not the behaviour described by the devs, either. I can only suggest that you subscribe to the kde-pim user list (https://mail.kde.org/mailman/listinfo/kdepim-users) where Kevin Krammer is doing his level best to identify the cause of user problems and advise.

So, it's a bug:
