ok, thanks for the explanation.
However, in this case, I have a _lot_ such entries which are also rather old.
The oldest ones are from July, but I find a few for every month up till today.
I have the feeling that something is not working correctly here.

It seems that all of these mails are in collections which are targets of a filter
(mailing list mails), so I have the feeling that there is still a bug in the filtering
code (and also I still do have duplicate mails in these folders, which sometimes disappear,
when clicking on them...)

which would mean - in case of an email downloaded from my POP account -
that the mail has been downloaded but not yet stored on disk ?

I have no imap account, just a POP account.

So how is the process here ? When is the mail stored on disk (in my maildir) and
when is the akonadi entry made ?
When does filtering kick in ?

Is that (openSuse 12.3) ~/.local/share/akonadi/file_db_data ?
In that dir I have 2810 files (all named something like 261372_r0), but only 513
entries in pimitemtable with null remoteId.
and yes, the (all?) contain mails. But again - I have files from about 22.Juli
until today. When shall they be moved into the maildir and deleted from here ?

I'm more interested in finding out WHY they are not in my maildir.

yup, I found that already, but the comments in there are sparse ...
